In OSM, a tag is a pair of this.

key-value

100

This model measures access by asking simply how far away the nearest one is.

Proximity model

100

The idea you actually care about vs. the number you use to stand in for it.

Construct vs. measure

100

The idea that a destination gets less useful the farther away it is.

Distance decay

100

This is "data about data": sources, last update time, confidence.

Metadata

200

Name the two spatial data models in GIS.

Vector, Raster
200

The three ingredients of spatial accessibility.

Supply, demand, reach

200

Same data, same steps, run again by someone else — do they get the same answer? This is the term.

Reproduction

200

These two contiguity rules define who counts as a neighbor.

Rook and Queen continuity

200

The 1950s transformation that made Anglo-American geography a spatial science, replacing regional description with statistical models.

The quantitative revolution

300

Land-use class, survey rank, temperature in Celsius, and population count are each measured at a different one of these four levels. Name them in order.

Nominal, ordinal, interval, ratio (partial credit for three of four)

300

Walk Score belongs to this model family, and one of its variants weights the first amenity more than the rest.

Cumulative model

300

Vagueness is one branch of poorly-defined-object uncertainty. Name the other branch and its two subtypes.

Ambiguity; discord and nonspecificity

300

We use Spearman rather than Pearson on accessibility scores because rank-based correlation survives these two features of the data.

Skew and outliers

300

Kitchin & Lauriault's term for the tangle of technology, politics, institutions, and infrastructure behind any dataset.

Data assemblage

400

Name three of the six components of spatial data quality.

Positional accuracy, thematic accuracy, logical consistency, temporal quality, completeness, fitness for use

400

Summarize Nearby is really two ArcGIS tools running in sequence. Name them, in order.

Buffer, summarize within
400

Changing catchment size, travel mode, or income threshold and seeing if the answer holds tests this.

Conclusion validty

400

Comparing access across three income groups calls for this test.

Kruskal-Wallis

400

Haraway's term for presenting knowledge as if it came from a detached, universal vantage point

The God trick

500

When two polygon layers don't line up, you get these two artifacts.

Slivers and gaps

500

You built your accessibility measure assuming people drive. Name the validity type that breaks when someone runs your exact method in a city where most people take transit.

External validity

500

Comparing your dataset to a reference dataset is this kind of validation; using the dataset's own attributes is this kind.

External and internal validation.

500

Aggregating Iowa data to counties vs. tracts can change your correlation. Name the problem.

Modifiable Areal Unit Problem

500

Name four of the seven Data Feminism principles.

Examine power / Challenge power / Elevate emotion and embodiment / Rethink binaries and hierarchies / Embrace pluralism / Consider context / Make labor visible
