note for clarification

I tag a lot of features and attributes (mostly bike lanes, trails, speed limits, but buildings and other things too) with source=survey. These are things I have visited and seen, but generally not mapped using GPS.

Edits of July 3--could use some guidance

Posted by EdHillsman on 3 July 2009 in English (English)

Three main areas of work today. One to finish entering the data from my visit to Weedon Island Preserve in northeast St. Petersburg, before I make another kayaking trip to another location tomorrow and get further behind. Completed footways and cleaned up the mainland coastline. The coastline that came with the map was coded inland of the mangrove areas, leaving them as offshore. I have edited the coastline to put them "onshore" and will deal with the islands once I figure out how to separate the mangrove part of the shore from "dry land" so that I can code the former as wetland=mangrove. There must be a way to draw a trace along the boundary between dry and wet, link it to the coastline on each end, and then declare the mangrove area to be a polygon, without having to retrace all the detail of the mangrove coastline. But I can't figure it out. Help and suggestions welcome.

The second to continue the ongoing process of recording land use, parking, etc. and untangling the surface streets near Brandon Mall.

The third to untangle the unbelievably complicated interweaving of I-75, the Crosstown expressway, and other limited-access-highway links to the west of Brandon Mall. It is complicated to drive, and now I am beginning to understand just why.

new gear

Posted by EdHillsman on 18 May 2009 in English (English)

Today I managed my first upload from my new Garmin Edge 305. I've been mapping in Tampa, FL since attending a mapping party in late February, mostly from observing while driving, walking, or cycling, and then tracing from the Yahoo imagery. Now I can start mapping some of the areas I know have been built up or otherwise altered since the images were made (like the rebuilt interchange north of here, which I started today and will gradually complete as I have occasion to pass through it in all directions), and start getting systematic about adding sidewalks.

I also have also sent a request in to the Hillsborough County GIS office, to confirm that the GIS data they have posted on their public site are indeed in the public domain (the site also has an atlas based on the data, which has a copyright, so it is possible the data may be copyrighted also). If the data ARE in the public domain, then I will be in touch with the emerging group that assists with large uploads, to get some of this onto the map. I should hear this week.

3/4, cleaned up TIGER data for Fletcher Ave between Bruce B Downs and I-75, dividing the street, adding the median/U-turn breaks, and completing the topology for the interchange with I-75. Changes made earlier in the week to add buildings near the interchange have appeared on the main map, but the cycle track edited from GPS at the same time has not, and I cannot find the padlock icon that the Potlatch instructions say to use to upload them.
