Contract Geospatial Developer – GeoServer / Esri JavaScript Integration
CompassData is seeking a contract Geospatial Developer to replace the current ArcGIS Server dependency supporting the CompassData Ground Control Point Archive web map with a GeoServer-based service workflow.
The current public GCP Archive map is available here:
The map is built using the Esri JavaScript API and currently consumes an Esri feature service published from ArcGIS Server in the CompassData data center. The goal is to replace that ArcGIS Server dependency with GeoServer while preserving the existing public map experience.
The GCP Archive contains approximately 90,000 ground control points stored in a Microsoft SQL Server database hosted in CompassData’s local VMware cluster in the Denver data center. Related metadata, GCP information, survey documentation, and pictures are stored in AWS S3. The archive data does not need to be migrated.
Project Scope
The selected developer will review the current Esri JavaScript web map, ArcGIS Server feature service, and supporting ArcGIS Pro configuration, then configure GeoServer in the CompassData data center to access the local Microsoft SQL Server GCP Archive database and serve GCP point locations to the web map.
The updated workflow should allow the existing or updated Esri JavaScript web map to consume GeoServer-served GCP location data, preferably through WFS or another approved GeoServer-supported service approach. The map must continue to display GCP locations, support metadata popups, maintain symbology and scale behavior where practical, and provide links or references to related metadata, GCP information, survey documentation, and pictures stored in AWS S3.
Key Deliverables
The expected deliverables include:
