GISP - Geographic Information Systems Professional GIS Application Development Questions and Answers

Question 1

A development team is building a public-facing web map that must display pre-rendered basemap imagery and allow users to query real-time vector data for traffic incidents from a municipal GIS server.
To ensure maximum performance and standards compliance, which combination of OGC web service types is most appropriate for the basemap and traffic data, respectively?

Accepted Answer

WMTS for basemaps and WFS for traffic data

Answer

WCS for basemaps and WFS-T for traffic data

Answer

WMS for basemaps and a KML file for traffic data

Answer

CSW for basemaps and WMS for traffic data

Question 2

A GIS developer needs to create a custom geoprocessing tool within an ArcGIS Pro project. The tool must automate a complex workflow that involves selecting features by location, calculating field values, and updating layers in the map's table of contents. Which Python library is specifically designed by Esri for this type of in-application scripting and automation?

Accepted Answer

ArcPy

Answer

GeoPandas

Answer

PyQGIS

Answer

GDAL

Question 3

Which of the following best describes a primary advantage of using an Agile development methodology over a traditional Waterfall model for a complex GIS application project where user requirements are expected to evolve?

Accepted Answer

It allows for iterative development and frequent stakeholder feedback, making it easier to adapt to changing needs.

Answer

It provides a fixed, comprehensive project plan and budget determined at the very beginning of the project.

Answer

It requires all system design and documentation to be fully completed and signed off before any programming begins.

Answer

It minimizes client interaction until the final product is ready for delivery to avoid scope creep.

Question 4

A developer is designing a mobile GIS application for field crews who will be collecting asset data in outdoor environments, often in bright sunlight and sometimes while wearing gloves. Which UI/UX design consideration is most critical to prioritize for this application's usability?

Accepted Answer

Incorporating large, high-contrast buttons and simple, clear icons.

Answer

Using a data-rich symbology to convey maximum information on the screen.

Answer

Relying on hover-based tooltips to provide feature details.

Answer

Designing a menu structure with many nested levels to keep the main map view uncluttered.

Question 5

In modern web GIS architecture, what is the primary function of a RESTful API, such as the ArcGIS REST API?

Accepted Answer

To provide a standardized, stateless method for client applications to request and manipulate resources on a GIS server.

Answer

To define the cartographic styling of map features using a language similar to CSS.

Answer

To maintain a persistent, stateful connection between the client and server for real-time data streaming.

Answer

To bundle and compress client-side code and assets to improve the initial load time of a web application.

Question 6

A GIS analyst must process a folder containing over 300 individual shapefiles each quarter. The workflow is identical for each file: project to a standard coordinate system, clip to a county boundary, and append the result to a single master feature class in an enterprise geodatabase. Which of the following represents the most efficient and repeatable method for accomplishing this task?

Accepted Answer

Writing a Python script using a library like ArcPy to iterate through the files in the folder and execute the geoprocessing operations.

Answer

Manually running the tools from the Geoprocessing pane for each of the 300 shapefiles.

Answer

Creating a single ModelBuilder model and manually changing the input parameter for each shapefile.

Answer

Importing all 300 shapefiles into the geodatabase first and then trying to run the tools on the entire batch at once.
