Project Goal

P1: The TPWD State Parks system offers approximately 9,000 publically reservable facilities spread across the state of Texas. The need to inventory amenities, collect measurements, and photograph each reservable facility came with the pending implementation of a new facility reservation system capable of site-specific reservations. The Planning & Geospatial Resources group implemented a hybrid cloud and desktop GIS solution to efficiently conduct and manage this extensive data collection effort.

P2: Alligator Gar, one of the largest freshwater fish in North America, historically ranged throughout the Mississippi and Gulf of Mexico River basins, from Florida to Mexico. A major contributing factor of the declining or extirpated populations is thought to be anthropogenic hydrologic alteration to their river system habitats. TPWD developed a floodplain inundation model to define the characteristics of these flood pulse events that lead to successful Alligator Gar recruitment.

Business Problem Solved

P1: The preexisting TPWD reservation database contains records (no location information) of sites based on the type of site available, such as a campsite with water and electricity, while occasionally storing some of the site amenities in one catchall text field. Data massaging and normalization, meticulous schema and attribute development, and massive statewide surveys to park managers helped construct a preliminary populated baseline database for field data collection. By using consistent data collection methodologies, facility attributes were collected or confirmed across the state. Individual site photos were collected to showcase these amenity details, which required photo naming standards to be implemented to ease photo organization.

P2: Assist Natural Resource scientist in determining and recommending flow needs for successful Alligator Gar recruitment.

Note Esri: we have 2 projects (p1/p2); p1 is State Parks using Collector for ArcGIS; p2 is Inland Fisheries using LiDAR.

Technology Implemented

P1: Collector for ArcGIS was integral to field data collection efforts using data hosted in ArcGIS Online. Utilization of enforced domain values and offline capabilities facilitated efficient and consistent data gathering, even in remote areas without cell service. An Operations Dashboard for ArcGIS was utilized by management to monitor data collection/confirmation progress during the project.

P2: With the increasing availability of high resolution digital elevation models from LiDAR, fine scale inundation mapping at these large spatial scales is becoming more feasible. Utilizing large spatial scale, high resolution DEMs in conjunction with a large spatial scale hydraulic model, it’s possible to provide a quantifiable and predictive tool to identify specific flood pulse characteristics. ArcGIS for Desktop Advanced and ERDAS Imagine were used to create a model of the Trinity River in Texas.
