Welcome to MapCollaborator™ San Diego Outside

The San Diego Co. Edition of MapCollaborator will help GreenInfo Network improve the California Protected Areas Database in the San Diego area.

Before adding or editing data, please review these EDITING GUIDELINES.

Choose from the actions below to review parks, add comments about parks, and propose the addition of new CPAD units (drawing on the map or upload your own GIS files).

You can also propose sites for park trail heads (staging areas hikers/riders would begin their trips) as well as a primary park entry for each park.

CPAD data used in this application is 2017a (April 2017). To get notices of when updates to CPAD are published, sign up for our notification list.

Comments and edits submitted in this MapCollaborator will be reflected in the twice-yearly CPAD updates and will not appear on this map until those updates are released.

Add or Edit a Park Area

Click the Draw button below, then draw a new park area or addition to an existing park on the map (please zoom in and be precise), and fill out attributes in the list.

Or, choose the Edit button and click on any park on the map to submit a recommended change to a park's attributes or geometry.

If you have GIS or KML/Z data, use the "Upload data.." panel below.

Select file to upload:
Note: Shapefiles must be zipped and include valid .prj

Use this tool to propose an edit to a pre-existing drawn or uploaded area.

Zoom to a location on the map, then click a previously-submitted area feature to start. The map will zoom to show the whole area, and will also show the vertices so you can drag them to reshape the boundary. This box will show a form where you can enter information about the location.

Note: Edits do not change existing data, but submit them for consideration.

Upload data for review

You can upload a zipped (.zip) ESRI shapefile (including .prj file) or a KML/KMZ file of properties to show on the map. Once uploaded, choose "Show on Map" to display the file. Choose "Send" to send the file to the site administrators, otherwise it will be deleted when you close MapCollaborator.

Start by uploading a file from your computer.

After reviewing your upload, you may submit to to COMaP by filling in the fields below. Or, you can clear the upload.

Please describe this dataset with a brief title and a more detailed description.

Add Trail Heads & Entry Points

Choose a park, then click on the site inside the park boundary to place a trail head (where you would go to actually start a significant hike or ride) or a main park entry point. Add a description and choose which the point type, then click "save".

Trail heads should be official or obvious trail access points; urban parks under 10 acres generally do not have trail heads.

Main park entries should be a single primary location where a road or main park trail/path can be accessed coming from outside the park (some park entry points may also be trail heads); some parks may be open from all sides and not have a main entry point.

Name of trail head or entry:


Type of point:

SUID of Park: (click park on map for details, start typing for hints)

Note: Shapefiles must be zipped and include valid .prj

Use this tool to propose an edit to a pre-existing drawn or uploaded point feature.

Zoom to a location on the map, and then click on a drawn point feature. The map will show a draggable marker so you can put the point into the correct location, and this box will show a form where you can enter information about the location.

Note: Edits do not change existing data, but submit them for consideration.

CPAD is an inventory of lands owned outright by public agencies and non-profits who manage them for open space purposes (wilderness, parks, forestry, wetlands, etc.), not including lands held under easements. Please observe the following guidelines when commenting or editing in MapCollaborator:

  1. CPAD is an OWNERSHIP inventory - we need to know who actually OWNS each parcel in the database (we also want to know if another agency MANAGES the land).
  2. Holdings in CPAD are mostly ALIGNED to assessor parcel boundaries. Parcel lines in most counties can be seen in the Google Base Map (G Streets tab in Base Maps) when zoomed in to street level, and can be used as reference for any shapes you create. In rural areas, some parcels lines may not match what's seen in aerial images but CPAD generally stays with the parcel boundaries - let us know if there are major alignment problems with any of these rural parcels.
  3. Google and Bing Street base maps have imperfect information on protected areas in California, particularly beyond neighborhood/city park scale - their green areas can create confusion when we overlay the much more accurate and complete CPAD data. Bing Maps parks data is somewhat better but still not complete or accurate for California.
  4. URBAN PARKS can be challenging to define - CPAD focuses on open space areas and generally does NOT include a city park or recreation site if it is primarily HARDSCAPE (courts, swimming pools, buildings). In the future, we may include these, but for now, please avoid including recreation sites that have more than half their total land area in hardscape.
  5. CPAD does NOT include SCHOOL fields unless they have an official agreement to be used as public recreation space.
  6. CPAD includes publicly owned golf courses (not privately owned courses) and some publicly owned cemeteries - these are all flagged in the CPAD database.
  7. SPECIAL DISTRICTS are public agencies that have their own board of directors (and therefore are not part of a city or a county). NON-PROFITS include land trusts and other such organizations qualified to hold land for permanent conservation purposes.
  8. CPAD does NOT include TRIBAL lands or MILITARY lands (except Army Corps of Engineers recreation sites) - data on these is maintained separately.
