We’ve started off the year with some updates to projects shown on our main GreenInfo web site, and on our MapsPortal site where interactive solution examples are found – check out these new images, and enjoy this issue of MapLines! 

AnchorCalifornia State Parks Community Fact Finder – Round 2

We recently updated the California State Parks Community Fact Finder website.  GreenInfo built this interactive website that is used by grant applicants to determine their required demographic and park acreage statistics (derived from GreenInfo’s CPAD data) for any defined project location.  Applicants for grants from $368,000,000 in Statewide Park Development and Community Revitalization bond funds (Prop. 84, 2008) must first qualify using the statistics in FactFinder, then submit a report generated by the website in their application. The program is intended to spur the creation of new parks in park deficient, economically disadvantaged communities.  In the first round, over 475 applications were received and $184 million awarded to 62 grantees.

AnchorESRI Food Desert Mapping

Team ESRI, publisher of ArcGIS software, has rolled out “The Food Desert Finder” a terrific interactive map which shows where there are gaps in access to supermarkets.  If access to nutritious food is limited or made difficult by factors such as cost or the distance traveled to obtain it, peoples’ health suffers – these areas that lack relatively easy access to nutritious, affordable food as popularly known as “food deserts.”  The ESRI Food Desert Finder is a searchable map that shows populations in poverty who live beyond a one mile walk to a supermarket and who lack other access to healthy fresh foods. Check out your community!

Transparent Images
Sometimes you want to make an inset map with a transparent background.  Unfortunately if you have a transparency set to in one of your layers in the inset map (usually a hillshade) the mxd will appear to be transparent on your computer screen but will export with a white background. See example below left.
  Example 1One work around for a transparent image in an mxd file is to bring it into Adobe Photoshop or other image editing program.  Create a separate .mxd that only contains what you want to show in your inset map, then export as a jpeg image file.  Bring the jpeg into Photoshop.  Select the background of the newly created jpeg with the magic want tool.  Then click on "Select" then click on "Inverse."  Make sure your "Layers" window is open (to open, click on "Window" then "Layers).  Now copy (Ctrl-c) and paste (Ctrl-v) to create a new layer.  Now click on the picture of the eye in the "Background" Layer window. (See example below with red circle around picture of the eye)Example 2. This turns background off. Now save as a new jpeg image file.  You now have a jpeg with no background.  To use this newly created jpeg as an inset map, you must export your main map (.mxd file) as a jpeg.

Bring both the main map jpeg and inExample 3set map with no background jpeg into Photoshop. 
Select inset map, copy image, and paste to your main map.  Position and resize as you wish.  You then get the result in the image to the left; an inset map with a transparent background.

Happy mapping from the GreenInfo Team!
