Daniel Yohey

GIS Manager, San Juan County, NM

Born in Arizona, raised in the San Juan Mountains, and laying roots in Aztec, NM for the past four years. My name is Daniel Yohey and I manage the GIS programs at San Juan County, NM. My experience in the geospatial world is still growing and I look forward to connecting with members of this group to build a strong network. My first love of maps grew from looking at atlases with my grandfather as well as looking out the window of planes at the earth below. I’m passionate about data, descriptive visualizations, and conveying stories of our striking landscapes in the Four Corners using GIS. In my free time, I enjoy being outdoors.

Camille Uentillie

Attended Fort Lewis College with my BA in Environmental Studies and GIS Certificate. I’m excited to continue my career in the GIS world. 

GIS Fun Fact: My first intro GIS course led me to my GIS program. GIS visually explained the No-DAPL pipeline project and who, what would be impacted. As a Native American, the software itself can provide a visual understanding when it comes to political aspects, land parcels, future developments and more.  

Sam Montoia

GIS Analyst, Archuleta County, Colorado

GIS Fun Fact: I asked ChatGPT for a rap about GDAL:

The GDAL, it's a library, you see

For handling geospatial data, it's key

It can read and write, with ease

Formats like GeoTIFF and shapefiles, please

It's open source, so it's free

For developers, it's a gift indeed With Python bindings, it's oh so sweet

For GIS projects, it can't be beat

From raster to vector, it can translate

With tools for projection, it's first rate

With OGR, it's even more great

For vector data manipulation, it's first rate

The GDAL, it's a must have tool For GIS professionals, it's no fool

With its power and versatility, it's cool

The GDAL, it's the geospatial data abstraction library, rule!
