GIS Services, Geospatial Data Analysis, Cartographic Design

ElephantFish was born on a warm summer's day in a ponderosa pine forest nestled in Pine, Colorado to provide GIS services to water resources/water rights, hydrogeologic, and environmental small businesses as well as nonprofit organizations that have no full-time GIS staff or businesses with GIS needs that may exceed the size of their GIS staff.

ElephantFish specializes in compiling, processing, and synthesizing geospatial data into products that are used to answer big (or little) questions.

ElephantFish is an ESRI shop...working in an ArcGIS Pro environment as well as ArcGIS Online and various ESRI mapping apps. Adobe Creative Cloud is used to add those special touches to cartographic mapping projects.
