When submitting a map to OWEB for a grant application, it is important that the coordinate you supply is in a readable format. Many formats exist because of the use of different projections in geographic information systems (GIS). A projection is the transformation of a three-dimensional space (Earth) onto a two-dimensional map. The State of Oregon has defined Oregon Lambert as the standard projection for government use.
Please provide your project area coordinate information in a readable format using the options listed below. It is not important to identify the projection used to create the map.
- Feet (use in the Oregon Lambert projection) (e.g. 1,952,416.309, 1,254,867.242)
- Decimal Degrees (e.g. -123.416, 45.216)
- Degree Minute Seconds (use in the Oregon Explorer Map Viewer) (e.g. -118° 11’37.079”W, 45° 5’39.728”N)
- Degree Decimal Minutes (e.g. -118 10.557, 45 4.454)
- UTM/MGRS – Universal Transverse Mercator/Military Grid Reference System (e.g. 18T 0439535 5024750)
Obtaining Lat/Long Coordinates
The Oregon Explorer Map Viewer can be used to create a map (see 'Creating a Map' section below) and also to obtain the latitiude/longitude coordinate required on grant applications. In following the provided guidance for creating a map, a step is included to obtain a latitude/longitude coordinate.
Oregon Latitude Longitude Locator
LocateOR is an application that will allow users to locate places in Oregon using a place name, a latitude and longitude, a legal description (township and range), a highway milepost or UTM coordinates.
Custom features of the application include:
- Location information derived from a point that you click on the map is automatically entered into the clipboard, so it can be pasted into an email, or other document.
- Bookmark and measuring tools.
Obtaining the 10-digit HUC
Watersheds are delineated by the U.S. Geological Survey using a nationwide system based on surface hydrologic features. The 10-digit HUC (hydrologic unit code) level identifies watershed units at the 5th field.
Oregon Explorer Map Viewer Instructions
- Go to http://oregonexplorer.info/
- Click on Oregon Explorer Map Viewer in the left hand column
- Switch the Map Theme to 'Watershed Restoration'
- Enter the town closest in proximity to your project in the search field.
- Results will be listed in the left hand column
- Click on 'Table View'
- Select the 'Place Names' tab
- Click on the name of the town once and the map will zoom to the location.
- Switch the menu on the left to see the map layers.
- On the ‘Explore Map’ tab select ‘Display for….’. In the drop down menu click on ‘Select None’
- Scroll down the menu toward the end and check only ‘Hydrologic Boundaries: 5th level (HUC 10)’
- Select the 'Point Identify tool and click once on the center of the map.
Note: the 'HUC number' that is displayed is the 10-digit HUC required for the grant application.

Creating a Map
A project location map is required with your grant application. In an attempt to standardize the map products received for projects, OWEB suggests using a specific online tool for creating a map. The Oregon Explorer Map Viewer offers user-friendly capabilities to create a printable PDF map. To create a map follow the instructions provided in the PDF below, a latitude/longitude coordinate will also be identified that can be used for the grant application. Click on the following link to download step-by-step instructions for using the tool.

Elements of a Good Map
The following describes elements that should be included on a map submitted to OWEB if the Oregon Explorer Map Viewer is not used to create the map.
- A legend or clearly labeled features
- A north arrow
- A latitude/longitude coordinate - either the center of the map or center of the project area
- A base map - either aerial imagery or a topographical map
- A map title - preferrably the project name
- A labeled hydrography layer
