# Querying Spatial Data with bcdata

#### 2026-02-06

This vignette illustrates how to use `bcdata::bcdc_query_geodata` to request and query geospatial data that has an associated Web Feature Service from the B.C. Data Catalogue. To illustrate, we will request and merge two spatial data sets from the catalogue—school district and greenspaces spatial data—and then examine the amount of park space contained within the boundaries of the Greater Victoria, Prince George and Kamloops/Thompson British Columbia school districts.

## Getting Started

First you need to load the package. We will also load the `sf` and `dplyr` packages to help us work with spatial data. You can learn more about the `sf` package here and `dplyr` here:

    library(bcdata)
    library(sf)
    library(dplyr)

## Geospatial Data in the B.C. Data Catalogue

The B.C. Data Catalogue provides many data sets with spatial information through a Web Feature Service (WFS). Technically speaking, this means if we have an internet connection we can issue HTTP requests to the catalogue and seamlessly import the response data into R as an `sf` objects. The `bcdata` package provides a means to a) choose which layer you want and b) use `dplyr` verbs to specifically tailor your request. A `dbplyr` backend is implemented so that requests are executed lazily meaning results are not transferred over the web until the user specifically calls the `collect` function. This approach mimics the `dplyr` verb translation to `SQL` seen for many database types. A good introduction to principles of `dbplyr` is available here.

## School District Data

Our first step is to extract the school district polygons from the B.C. Data Catalogue. This layer is described using this command:

    bcdc_get_record("78ec5279-4534-49a1-97e8-9d315936f08b")
    #> B.C. Data Catalogue Record: School Districts of BC

    #>  through locally elected school boards.

    #>  bcdc_query_geodata('78ec5279-4534-49a1-97e8-9d315936f08b')

This data is the boundary of each school district. The key information in this metadata is that the layer has a resource in `"wms"` format —which means it is available through a Web Feature Service. From this we know we can make use of `bcdc_query_geodata`.

This is the initial query to the data in the catalogue. What has been returned is not the actual data but rather a subset to help you tune your query. The printed output of this query offers several useful pieces of information. Because we have queried with a unique ID, we are shown the name of the record. We also receive instruction that using `collect()` will retrieve a given number of features and fields present for this query. Lastly, there is a reminder that what is printed is only the first 6 rows of the record. Since we are limiting the scope of analysis to the Greater Victoria, Prince George and Kamloops/Thompson school districts, we want to ask the catalogue for only those polygons just like we would in a typical `dplyr` workflow:

    bcdc_query_geodata("78ec5279-4534-49a1-97e8-9d315936f08b") %>%
      filter(SCHOOL_DISTRICT_NAME %in% c("Greater Victoria", "Prince George","Kamloops/Thompson"))
    #> Querying 'school-districts-of-bc' record

    #>   <chr>              <int> <chr>                                 <int> <chr>                   <dbl>

    #> # ℹ 4 more variables: FEATURE_LENGTH_M <dbl>, OBJECTID <int>, SE_ANNO_CAD_DATA <chr>,
    #> #   geometry <POLYGON [m]>

To further tune our query, we can also request only the columns we want. Really we only want the school district column and the spatial information. During an actual analysis, it is possible that you may need to initially collect more data than you want to determine value to subset by. For example, there is currently no way to ask the catalogue for all possible unique values of `SCHOOL_DISTRICT_NAME`. Is that case the data will need to be brought into R and unique values will need to be determined there.

    bcdc_query_geodata("78ec5279-4534-49a1-97e8-9d315936f08b") %>%
      filter(SCHOOL_DISTRICT_NAME %in% c("Greater Victoria", "Prince George","Kamloops/Thompson")) %>%
      select(SCHOOL_DISTRICT_NAME)
    #> Querying 'school-districts-of-bc' record
    #> • Using collect() on this object will return 1 features and 5 fields
    #> • At most six rows of the record are printed here
    #> ────────────────────────────────────────────────────────────────────────────────────────────────────
    #> Simple feature collection with 1 feature and 5 fields
    #> Geometry type: POLYGON
    #> Dimension:     XY
    #> Bounding box:  xmin: 1126789 ymin: 821142.1 xmax: 1528155 ymax: 1224202
    #> Projected CRS: NAD83 / BC Albers
    #> # A tibble: 1 × 6
    #>   id                             ADMIN_AREA_SID SCHOOL_DISTRICT_NAME SCHOOL_DISTRICT_NUMBER OBJECTID
    #>   <chr>                                   <int> <chr>                                 <int>    <int>
    #> 1 WHSE_TANTALIS.TA_SCHOOL_DISTR…            328 Prince George                            57      562
    #> # ℹ 1 more variable: geometry <POLYGON [m]>

Note that in the `select` statement, we did not explicitly ask for the spatial data and also that there are several columns present that we didn’t select. This is because within each data set in the data catalogue, there are several columns that will always be returned regardless of what is selected. If you really don’t want those columns after you `collect` the data, which we will take care of right now, you can drop them:

    districts <- bcdc_query_geodata("78ec5279-4534-49a1-97e8-9d315936f08b") %>%
      filter(SCHOOL_DISTRICT_NAME %in% c("Greater Victoria", "Prince George","Kamloops/Thompson")) %>%
      select(SCHOOL_DISTRICT_NAME) %>%
      collect()

Again note here that we have assigned the object a name and added the `collect` statement. This step happens when you have selected the data you want and wish to begin working with it in R like a normal `sf` object. For example, we can now plot these three school districts:

    plot(st_geometry(districts))

plot of chunk districts

Now that we have the spatial boundaries narrowed by specific school districts we can perform some spatial operations to determine parks in the school districts.

## Greenspaces Data

For the purposes of this example, let’s consider this greenspace layer in the catalogue. This layer is described here:

    bcdc_get_record("6a2fea1b-0cc4-4fc2-8017-eaf755d516da")
    #> B.C. Data Catalogue Record: Local and Regional Greenspaces
    #> Name: local-and-regional-greenspaces (ID: 6a2fea1b-0cc4-4fc2-8017-eaf755d516da)
    #> Permalink: https://catalogue.data.gov.bc.ca/dataset/6a2fea1b-0cc4-4fc2-8017-eaf755d516da
    #> Licence: Open Government Licence - British Columbia
    #> Description: This dataset contains spatial and attribute information for local and
    #>  regional greenspaces in British Columbia. Local and regional greenspaces are municipal
    #>  or regional district lands designated by local government agencies and managed for
    #>  public enjoyment, ecosystem or wildlife values. Spatial boundaries were sourced from
    #>  municipal and regional district web sites, which in some cases provide datasets under
    #>  Open Government Licence, and in other cases, publicize parks and greenspaces on web maps
    #>  or pdf maps. Boundaries were edge-matched to the ParcelMap BC cadastre.  This spatial
    #>  layer contains multipart polygons.
    #> Available Resources (2):
    #>  1. WMS getCapabilities request (wms)
    #>  2. LocalRegionalParksAttributeValues (xlsx)
    #> Access the full 'Resources' data frame using:

    #> Query and filter this data using:
    #>  bcdc_query_geodata('6a2fea1b-0cc4-4fc2-8017-eaf755d516da')

Again we recognize this is WFS-enabled geospatial data, which means we can make use of `bcdc_query_geodata`.

    bcdc_query_geodata("6a2fea1b-0cc4-4fc2-8017-eaf755d516da")

Since we are interested in only “Park” data we can subset our query:

    bcdc_query_geodata("6a2fea1b-0cc4-4fc2-8017-eaf755d516da") %>%
      filter(PARK_PRIMARY_USE == "Park")
    #> Querying 'local-and-regional-greenspaces' record

    #> Projected CRS: NAD83 / BC Albers
    #> # A tibble: 6 × 20
    #>   id      LOCAL_REG_GREENSPACE…¹ PARK_NAME PARK_TYPE PARK_PRIMARY_USE REGIONAL_DISTRICT MUNICIPALITY
    #>   <chr>                    <int> <chr>     <chr>     <chr>            <chr>             <chr>
    #> 1 WHSE_B…                     49 Woodward… Local     Park             Metro Vancouver   Richmond
    #> 2 WHSE_B…                     50 Woodward… Local     Park             Metro Vancouver   Richmond

    #> #   SE_ANNO_CAD_DATA <chr>, geometry <POLYGON [m]>

Here we see that this greatly reduces the number of features that we are dealing with (and correspondingly the amount of data that needs to be transferred over the web). Remember also that we still have not actually requested the full data set. This is just still a preview. Also this query still includes all municipal parks in BC while we only want the ones in the three school districts - the polygons defined by the `districts` object. To find that subset of parks we can make use of the built-in geometric operators which allow us to perform spatial operations remotely fine tuning our query even further. Here using the `INTERSECTS` function is appropriate and since this is a last tuning step, we can call `collect` and assign a name to this object. These requests can sometimes take quite a long:

    districts_parks <- bcdc_query_geodata("6a2fea1b-0cc4-4fc2-8017-eaf755d516da") %>%
      filter(PARK_PRIMARY_USE == "Park") %>%
      filter(INTERSECTS(districts)) %>%
      collect()
    #> The object is too large to perform exact spatial operations using bcdata.
    #> Object size: 948576 bytes
    #> BC Data Threshold: 500000 bytes
    #> Exceedance: 448576 bytes
    #> See ?bcdc_check_geom_size for more details
    #> A bounding box was drawn around the object passed to INTERSECTS and all features within the box will be returned.

Plotting both the filtered parks data and the district polygons reveals an important consideration when using `bcdata`:

plot of chunk district_parks

In this example, many parks not contained within the school districts are included in the `districts_parks` object. This is because rather than a full intersection, `bcdata` draws a bounding box around all the polygons that are doing the intersection (in this case `district`) and does the intersection based on that bounding box. This behaviour is imposed by the Web Feature Server but controlled via the `bcdata.max_geom_pred_size` option (See `?bcdc_options` for default values). Using this example, you can check to see if the size of the `districts` object exceeded the current value of `bcdata.max_geom_pred_size`:

    bcdc_check_geom_size(districts)
    #> The object is too large to perform exact spatial operations using bcdata.
    #> Object size: 948576 bytes
    #> BC Data Threshold: 500000 bytes
    #> Exceedance: 448576 bytes
    #> See ?bcdc_check_geom_size for more details

Drawing the bounding box illustrates this point:

plot of chunk bbox

We are left with two options to get around this problem. First, we can simply do some additional processing with the `sf` package. Specifically we can use a spatial join to assign parks into their respective district:

    districts_parks_join <- districts_parks %>%
      st_join(districts, left = FALSE)

plot of chunk dp_join

A second approach is to set an internal option (`bcdata.max_geom_pred_size`) and increase the threshold of when a bounding box is drawn. Options are set in R like this:

    options("bcdata.max_geom_pred_size" = {object size in bytes})

The value of `bcdata.max_geom_pred_size` is set conservatively so that requests to the Web Feature Service are more consistently successful. Increasing this value may result in invalid requests.

Finally, to address our original question of which school district has the most municipal park space we can calculate the area of each park polygon and then sum those areas by school district:

    districts_parks_join %>%
      mutate(area = st_area(geometry)) %>%
      st_set_geometry(NULL) %>%
      group_by(SCHOOL_DISTRICT_NAME) %>%
      summarise(total_area = sum(area)) %>%
      arrange(total_area)
    #> # A tibble: 1 × 2
    #>   SCHOOL_DISTRICT_NAME total_area
    #>   <chr>                     [m^2]
    #> 1 Prince George         11793481.

### A note about using local R functions in constructing filter queries

Suppose we now want to find all of the parks within 1km of the school districts we are interested in. We can use `sf::st_buffer()` to make a buffer around the `districts` object, then intersect that with the greenspaces data. Note that `st_buffer()` needs to be executed in R on our computer, to create the buffered area that is sent to the WFS server to perform the `INTERSECT` query remotely. We tell `filter()` to evaluate that piece of code locally by wrapping it in a `local()` call:

    greenspaces_around <- bcdc_query_geodata("6a2fea1b-0cc4-4fc2-8017-eaf755d516da") %>%
      filter(INTERSECTS(local(st_buffer(districts, 1000)))) %>%
      collect()

## Additional Useful Functions

There are a couple of other functions in `bcdata` that are useful to know when working with spatial data from the catalogue. `bcdc_describe_feature` gives the column names, whether the column is selectable, and the column types in both R and on the remote server:

    bcdc_describe_feature("6a2fea1b-0cc4-4fc2-8017-eaf755d516da")

This is a helpful initial step to learn column names and types when you construct your query.

Another useful function is `show_query()` which provides information on the request issued to the remote server:

    bcdc_query_geodata("6a2fea1b-0cc4-4fc2-8017-eaf755d516da") %>%
      filter(PARK_PRIMARY_USE == "Park") %>%
      filter(INTERSECTS(districts)) %>%
      show_query()

    #>  1528155 821142.1, 1528155 1224202, 1126789 1224202, 1126789 821142.1)))))

This output is what being created by the dplyr code outlined above.

## Using B.C. Geographic Warehouse (BCGW) layer names

If you are familiar with the B.C. Geographic Warehouse (BCGW), you may already know the name of a layer that you want from the BCGW. `bcdc_query_geodata()` (as well as all other related functions) supports supplying that name directly. For example, the record for the B.C. airports layer shows that the object name is `WHSE_IMAGERY_AND_BASE_MAPS.GSR_AIRPORTS_SVW`, and we can use that in `bcdc_query_geodata()`:
