Mapping - GIS Services


Pritchard & Abbott, Inc., (P&A) has been providing mapping services for over 25 years to Appraisal Districts and other clients  statewide. We have a unique and intimate knowledge of what Appraisal Districts and other local entities need and want - after all, we’re in the same business!

P&A takes pride in providing a hands-on approach in our mapping services. The information stored in our mapping systems can be retrieved from external digital data and other sources. We also generate and trade information with surveyors, engineering firms, local entities, and even other Appraisal Districts. This user-friendly and intuitive method of retrieving and handling data makes it easier and faster for the appraiser to find all the necessary information needed to locate and identify property ownership.


ESRI Client & Public Hosting Web-Based Software

This web-based software uses layer formats designed with custom GIS tools prepared for appraisal district needs. The development of tools for web-based software is produced on input from appraisal district employees. P&A is using ESRI web-based software to support many layers other than only surface ownership and abstract/surveys. It uses sophisticated raster and vector functionality created by application developers that allows you to capture and edit data with a wide range of user tools. Included in these features are: COGO input, data management, data analysis, and visualization of geographical information with a solid database interface. Vector layers such as 911 road, 911 addresses, soils, FEMA, pipeline along with city and state boundaries can be added, if provided. Because almost all mapping projects require some degree of customization, ESRI web-based products are designed to be an application development platform as well as an end-user product.



This process is where Pritchard & Abbott, Inc., will convert a set of maps provided by the client via Mylar or paper copy format to a digital format. This is normally the fastest way to provide a digital map for our clients. However, by itself it is not always the most accurate map to use. With additional applications concurrently loaded, such as Ortho-Photography, external image data and/or TX-DOT information, we can produce a line-drawn map that will make the mapping more accurate. Also able to convert many other digital formats to comply with said software.


Mapping Maintenance 

This is the application whereas the ownership changes and splits after a mapping project has been completed are added as needed. We pull data from our real estate database onto existing map files so the data can be seen and queried on the maps.


Software Maintenance 

As part of our continuing customer support, Pritchard & Abbott, Inc., will constantly monitor for all updates, changes, and other advances, and make them available as soon as possible.


Ortho-Photography & Survey Lines

For the most accurate and useful digitized mapping software and service, it is highly recommended to add Ortho-Photography & Survey lines to create, start, and/or complete maps. Pritchard & Abbott, Inc., can provide this information upon request.
