[site] Free Geography Tools

Back in February, I had a long post about the FCC’s conditional approval of LightSquared’s wireless broadband proposal. This waiver was vigorously opposed by the GPS industry because tests by Garmin showed that it would seriously disrupt GPS in areas where it was implemented. Read the post for a full rundown, but briefly LightSquared’s plan requires high-power transmissions in frequencies immediately adjacent to the GPS band, which drown out the GPS signal entirely. LightSquared dismissed these Garmin results, stating in a comment to my post: … the Garmin tests that you refer to were not made under appropriate circumstances so the results are not accurate indications of how our network will perform. To get a real examination of the situation, tests must be conducted in the proper band and with the right filters.

[site de carto] explication de prettymaps prettymaps is an experimental map from Stamen Design. It is an interactive map composed of multiple freely available, community-generated data sources: All the Flickr shapefiles rendered as a semi-transparent white ground on top of which all the other layers are displayed.

Earth Survey This page provides links to free applications that run in the Google Earth desktop client, the Google Earth mobile client (ESMobile), and the Google Maps API (ESMaps). Earth Survey is a collection of geodetic tools that run in Google Earth. Most of the applications have geographical extents associated with the United States, but MagDec, RINGS, and XYZGE work anywhere on the globe, while HCBM will be of interest primarily to Central Florida surveyors. QUADS and PLSGE provide easy access to data and image services from the USGS and BLM, respectively. NGSCS is a graphical front end for the NGS station list utility, and seven of the tools (DeflecGE, GeoidGE, MagDec, NADGE, SPCGE, VERGE, and XYZGE) are graphical front ends for programs from the NGS Geodetic Tool Kit. Download the Earth Survey Shortcut for easy access to Earth Survey tools from the Google Earth embedded web browser.

[site] Cartographie esthétique prettymaps The short version is simply that there's a huge amount of data being sent across the network and then processed and finally rendered by your computer. We've looked at the logs for the machine hosting prettymaps and it seems happy enough serving all the requests that people are sending it. The other reason is that the data hasn't been compressed or optimized as much it could be. For example, the four separate image layers could be collapsed in to a single layer. Likewise the data layers, although we've found a few more places to tighten things up since we first launched. We haven't done a lot of optimizations by design because we wanted to leave all the plumbing exposed so that people could look at it and learn from it and, hopefully, build something new.

Geoportale Nazionale The National Geoportal of the Ministry of Environment and Protection of Land and Sea, operates within the regulatory framework established by Legislative Decree no. 32/2010 and subsequent amendments and additions, the Italian transposition of the European Directive 2007/2 / EC establishing an Infrastructure for Spatial Information in the European Community (INSPIRE). Article.8 paragraph 2, of Legislative Decree no. 32/2010 provides that the National Geoportal is the national access point for the aims of the INSPIRE Directive thereby providing a basis for the competent authorities, third parties, and private citizens to seek the spatial information available. The National Geoportal is at the core of a network architecture designed as a federated network in which each node is "connected" to the central access point that is the National Geoportal itself.

Better web cartography with dot density maps and new tools « News Apps Blog Between Brian, Joe, and myself there hasn’t been a time in the last six months where at least one of us wasn’t working with census data. Back in February we attacked the less-detailed (redistricting) data for print and the web. In April, May, and June we contributed to a joint effort with an esteemed cadre of news nerds to develop census.ire.org, a site intended to make it easier for journalists to report from census data.

Too Many Markers! - API Google Карт Luke Mahe and Chris Broadfoot, Google Geo APIs TeamDecember 2010 Introduction Some applications are required to display a large number of locations or markers. Despite the v3 JavaScript API's significant improvement to performance, naively plotting thousands of markers on a map can quickly lead to a degraded user experience.
