We also encourage you to call before visiting any county office.
We are a division of Clackamas County's Technology Services department. One of the advantages GIS provides is the ability to assist in the decision-making process by providing an additional tool to analyze and compare numerous geographic data layers along with traditional databases.
Questions GIS can answer include:
- Location "Where is it?"
- Condition "What is at?"
- Trends "What has changed since?"
- Patterns "What spatial patterns exist?"
- Modeling "What if?"
Clackamas County GIS offers an online map and information retrieval tool called CMap. With this tool you can simply type an address or tax map number and receive information about that particular parcel. A map accompanies the information with the option to display aerial imagery.
The county's GIS contains a wealth of information that can be used with specialized software. From the buttons on the left, you can get more information on our various products and services.
Web Mapping Applications
We are now offering an online store to make ordering maps, photos and mailing labels convenient.
Orthophotographs are digital aerial photos, taken perpendicular to the ground that have been rectified to the earth's surface. These photos can be used by themselves or we can overlay other GIS information on them such as tax lots, contours, soils, etc.
Through our custom mapping services, you can specify:
- scale and area
- page size and layout
- titles and labeling
- data layers needed
A paper version of the County Road Map is available on request. This large map is unfolded and has two sheets. Sheet one shows the entire county. Sheet two shows the urban areas and rural communities in more detail.
Clackamas County GIS Data Portal
The products accessed through the Clackamas County GIS Data Portal are for informational purposes and may not have been prepared for, or be suitable for legal, engineering, or surveying purposes. All data is provided as is, at no charge, and no further support is offered by Clackamas County GIS including offering the data in different formats. Data is offered as shapefiles. Users of this information should review or consult the primary data and information sources to ascertain the usability of the information. Metadata does accompany each shapefile. The use of these shapefiles is governed by our GIS Data Licensing Agreement, which will be presented upon selecting a layer to download, and must be agreed to before the data can be downloaded. Data will be updated periodically and the update date will be reflected in the metadata.
