| Coordinate Formats |
|
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.
Coordinate Formats:
Feet (if using the Oregon Lambert projection, the coordinate will be in feet)
e.g. 1,952,416.309, 1,254,867.242
Decimal Degrees
e.g. -123.416, 45.216
Degree Minute Seconds (if using the Oregon Explorer Advanced Mapping Tool, the coordinate will be in degree minutes seconds)
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 Advanced Mapping Tool 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.
In addition, the Oregon Department of Forestry has developed a web application to obtain latitude/longitude coordinates. The tool is a good resource for obtaining the coordinates required on an OWEB grant application if the Oregon Explorer Advanced Mapping Tool is not used.
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.
Download a PDF of these instructions. (complete with screen shots)
Oregon Explorer – Advanced Mapping Tool
1. Go to http://oregonexplorer.info/
2. Click on 'create a restoration project map' in the left hand column
3. Turn on the 5th Field HUC layer.
Note: this is found on the column on the left of the map under the ‘Watersheds and Hydrologic Units’ sub-folder of the ‘Water and Air’ folder.
4. Select the identify tool  then click on a watershed boundary, the detailed information about the watershed will be displayed in the left hand column.
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 Advanced Mapping tool offers user friendly capabilities to create a printable PDF map. In creating a map following the instructions 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 Advanced Mapping Tool is not used to create the map.
1. A legend or clearly labeled features
2. A north arrow
3. A latitude/longitude coordinate - either the center of the map or center of the project area
4. A base map - either aerial imagery or a topographical map
5. A map title - preferrably the project name
6. A labeled hydrography layer
Free Oregon spatial data can be downloaded from the Oregon Spatial Data Library.
