Services, Resources and Tools for Mapping DataLong ago, putting together a map of data points would be the sole domain of a skilled GIS practitioner employing an application like ArcView. These days, particularly with the advent of Google Maps, Yahoo Maps and OpenStreetMap, et al., there are a multitude of options for an individual to employ in displaying data geographically. Of course, there are, and will always be, technical options that require some level of programming chops. Fortunately, the pool of drop dead easy implementations that anyone can throw together with ease has grown a lot over the last few years. Then, there is the growing middle ground, lying somewhere between easy but rigid and difficult but flexible. Personally, I tend to hover in this netherworld, leveraging existing code, services or tutorials when possible but occasionally finding myself diving into the more technical areas when necessary and learning a lot in the process.

For those of you out there who might be interested in mapping data, I’ve put together a collection of links to a variety of services, code samples, resources and tutorials I’ve found useful in the past. These links range from new services that barely require anything more than a spreadsheet to complicated frameworks that require a great deal of technical knowledge. This is by no means all encompassing and if you happen to have additional links you’d like to share, feel free to leave them in the comments.

First Look at Natural Earth Vector

Friday, June 12th, 2009

Tom Patterson and I collaborated on the precursor to his first Natural Earth Raster project several years ago and we now preview Natural Earth Raster + Vector, a new free product due Fall 2009 that complements and expands on the previous work by providing detailed GIS linework at the 1:15,000,000 (1:15 million) scale and new versions of the raster product (including cross-blended hyspometric tints). The Washington Post, where I work, is contributing 2 more vector GIS base maps at the 1:50m and 1:110m scales and new versions of Natural Earth Raster will be released for those scales. This is a NACIS and mapgiving co-branded product with assistance from the University of Wisconson-Madison cartography lab, Florida State University, and others.

Please attend the October NACIS 2009 map conference in Sacramento, California for the unveiling.

Yahoo Maps Now Shows Neighborhood Areas, Of Sorts

Wednesday, April 16th, 2008

This entry reprinted from IMGoph, a cartographer and geography nut, using Washington, DC as an example, view original post on his blog. (Ed-This was picked up later by The Washington Post’s Rob Pegoraro in his Faster Forward blog this week, view that post.) 

so check this out. yahoo maps has a new feature on the site. google maps has neighborhood labels on their city maps, but it looks like yahoo has decided to try to go them one better. they’re shading the neighborhoods in on their maps.

problem is, their choice of what makes a neighborhood and what doesn’t leaves a heck of a lot to be desired.

here are a couple of examples from the screen capture you can see to the right:

– lots of neighborhoods are missing. this map has no shaw, no eckington, no bloomingdale, no ledroit park.

– the neighborhoods they do label have grown to eat up a lot of these missing neighborhoods. edgewood has swallowed eckington, bloomingdale, stronghold, and truxton circle. off the map here, ivy city has swallowed trinidad, and you can see that logan circle has eaten up shaw. ledroit park is now part of “cardozo”, which not a lot of people use for the u street area, but i think it’s not a bad choice.

it’s a good start, yahoo, but you need to refine this before it’s really useful.
