What is GIS?

Geographic Information Systems (GIS) is a computer-based technology that merges maps (called spatial information) with database (called tabular information). GIS superimposes or integrates layers of information. These layers can be aerial photos, water, roads, tax lot parcels, zoning, etc. GIS pulls together information and presents it in a graphic or map format. More information about GIS can be found at

Clatsop County GIS

Clatsop County began its GIS program in 1998 by converting all our assessor's tax maps from paper to digital format. When completed, the digital tax maps will provide the foundation for other layers of information, such as zoning and tax code districts.

GIS Data & Maps for the Public

We provide a few static maps in PDF format below. These maps require Adobe Reader to view and print. The maps were originally produced at different sizes from 11 by 17 inches to 36 by 48 inches. Adobe Reader will reduce these to 8.5 by 11 inches to print on standard printers. Maps may take several minutes to download. If you would like to purchase GIS data from us in shapefile format, the fees are $25/shapefile or $100 for all of our public shapefiles. Please contact the GIS Coordinator at gisinfo [at] or (503) 325-8662 if you’d like to purchase data.
