What you will make

A one-page map that answers a modest local question, such as where public destinations sit in relation to a study-area boundary.

Planning decisions are tied to place. GIS lets you compare where things are, what is near them, and how their attributes differ. A map is useful when its question, geography, data, and limitations are clear; it is not proof that a pattern has a particular cause.

• Explain how a GIS layer links geographic features to attributes.
• Distinguish a map's observed pattern from an explanation or prediction.
• Describe the question, area, source, and limits of a simple planning map.

Watch and try it

Work through the method

1. Start with a question

   Choose a question answerable from locations and attributes, such as which destinations fall inside a supplied downtown boundary. Avoid questions about causes, demand, or safety unless the data can support them.

   Check your work: Write the question as one sentence and name the study area.

2. Identify the pieces

   A GIS feature has geometry, such as a point or polygon, and attributes stored in fields. A layer is the map's connection to that dataset plus its display settings; it is not a separate copy of the underlying data.

   Check your work: For one layer, name its geometry and two fields that matter to your question.

3. Open a project

   In ArcGIS Pro, start a Map project and add the supplied boundary and destination data. If the package is unavailable, use any instructor-provided local point and polygon layers; do not assume a public portal login is available.

   Check your work: Both layers draw in the map and their source names are visible in Contents.

4. Read the evidence

   Open each attribute table, inspect the field names and several records, and confirm that the study-area boundary and points refer to the intended place. Note missing values and the data date if supplied.

   Check your work: Record one source limitation that could affect interpretation.

5. Make a restrained map

   Use a clear title, distinct symbols, and a useful extent. Keep the boundary visible without obscuring points. Add a short source note and state what the map does not establish.

   Check your work: A reader can identify the place, mapped features, and question without your explanation.

6. Export and explain

   Export the map as a PDF or PNG and write two sentences: one observation supported by the map and one conclusion the map alone cannot support.

   Check your work: The exported file opens and the caveat is readable.

Map one local relationship

1. Use a supplied study boundary and point layer, or an equivalent practice dataset provided with the course.
2. Inspect the table and note the source date and any missing or uncertain locations.
3. Style the features so the relationship is legible at the exported page size.
4. Add a title, source note, and a one-sentence limitation.

Bring the method into a product

• One-page map answering a place-based question
• Two-sentence observation and limitation note

Suggested formats: PDF, PNG.

Reflect: What additional evidence would you need before turning your map observation into a planning recommendation?

Avoid these mistakes

• A visible cluster does not explain why features cluster.
• A blank map can reflect missing or filtered data, not absence on the ground.
• Do not call a layer current or complete unless its source documents that.
