Aransas County Appraisal District

Rockport, Texas

Aransas County Appraisal District (ACAD) had a contractor convert CAD parcels to an ArcInfo coverage and had also bought ESRI software based on recommendations made by a contractor. Tessellations was tasked to use the existing hardware/software infrastructure and create a multi-user GIS framework. After meeting with the users, Tessellations designed and implemented the appraisal Geodatabase and integrated it with their Computer Aided Mass Appraisal (CAMA) system. Tessellations installed a GIS sever and integrated it into their existing enterprise computing environment. The system includes several floating licenses and utilizes ArcGIS Server software to serve up maps to other internal and external users with a web mapping service.
