EcoGIS / CAPS-Scenario-Builder

The CAPS Scenario Builder will allow government officials, conservation groups and others to submit "scenarios" for proposed changes to land cover and infrastructure so that these changes can be assessed for their impact on ecological integrity.

Point symbols #20

Closed ScottJackson closed 12 years ago

ScottJackson commented 12 years ago

I’m thinking that it might be good to have different symbols for the various point features (e.g. culverts/bridges=dot, dams=box, terrestrial passage=triangle, tidal restrictions=hexagon). I worry that for complicated scenarios a user might lose track of what features are what.

I think this is a good idea might be possible in the future, but it is not easy to do. I added the cross and triangle to allow users to distinguish between new points, deleted points and modified points, which was quite difficult, but I thought it important, so I did it. Right now, users can use the identify tool and/or the attribute table to figure out what is what. It would probably be a really good idea to add the ability to select features on the map canvas by selecting them in the attribute table. Lets have a discussion about what your plans are for a first release to users, and whether you want to hire me to add sftp, project management and other features.

That's fine.

I was able do this. A nice addition!

I changed symbology so that features on the edit_scenario points layer appear as follows: culverts/bridges = filled circles, dams = rectangles, wildlife crossing structures = pentagons and tidal restrictions = stars. All symbols remain red. The red cross for deletions and the red triangle for modifications remains for all point scenarion edit types (i.e. circles, rectangles, pentagons and stars). There is no change to the base layers' symbology. The pentagon looks like a small house, so it seems to match the word "structures," which helps me to remember what the symbols mean.

Issue closed.
