2010 Census: Children less than five years old in Chicagoland By Chris Groskopf and Brian Boyer Aug. 7, 2011 This map shows the distribution of children less than five years old in Cook, Lake, Kane, McHenry, Kankakee, Kendall and DuPage counties as reported by the 2010 U.S. Census. Each dot represents a single child Read the story:New U.S. census numbers herald a greater Latino presence in the Chicago area Move your mouse over the map for details. *What do these numbers mean? This map shows one dot for each child less than five years old as reported in the 2010 U.S. Chris Harrison - GPS Project This page describes the steps I went through in my project to connect a Garmin eTrex Summit GPS device to a Nikon D200 camera body in order to record location information in the EXIF data of images captured using the setup. While this procedure worked fine for me, I do not take any responsibility for you or your equipment should you try this yourself. All images can be found in the "Equipment" photoset on my flickr account, here. A parts list in PDF format can be downloaded here. There are seven steps: Step 1 - The circuit diagram and initial circuit layout Step 2 - Soldering the components and jumpers to the breadboard Step 3 - Constructing the box to house the GPS Step 4 - Second stage of soldering, fixing camera and GPS cables, and fitting remote release socket Step 5 - Making the false floor to support the GPS and protect the circuitry and components Step 6 - Painting/finishing Step 7 - Constructing new Garmin to PC cable and downgrading GPS firmware
Немного OSM и OpenLayers для корпоративных систем Привет Хабр, сегодня я расскажу немного про использование osm для предприятий и b2b. А именно, как и зачем перейти от google maps api к osm, openlayers и счастью. Первый вопрос, который непременно возникнет: зачем? Начнем с того, что использование google maps api для непубличных сервисов ограничено условиями предоставления сервиса. Второе: апи карт гугл — это именно апи карт гугл, а не апи для отображения всего, что напоминает карту. Т.е. если вам захотелось отображать другую подложку или добавить растровый слой, отрисовываемый сервером в локальной сети предприятия, готовтесь лепить костыли. Предположим, я вас убедил. Первое, подключаем карту в openlayers. var map = new OpenLayers.Map('map'); var layer = new OpenLayers.Layer.OSM('OSM mapnik'); map.addLayer(layer); map.zoomToMaxExtent(); Крупные компании зачастую могут себе позволить купить картографический сервер и карты и раздавать их в локальной сети через wms или tms. Соответсвенно, меняем строку создания слоя для wms на для tms: пишем
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. And to prepare for this recent release, we even spent a week hacking near-complete prototype maps using data that the census had already released, Kings County, New York. We learned hard lessons about the scale and nuance of the census in the last few months, and along the way, further built out our toolkit for making maps. Last week the Census Bureau released detailed (summary file) data for Illinois, and we used our new tools to produce a couple of maps we’re pretty excited about: These maps demonstrate a map style we haven’t attempted before: dot density mapping.
Importing Imagery There are three main ways you can import imagery into Google Earth: Image overlay - (Add > Image Overlay) This is an image that is draped over the surface of the earth (though it can appear elevated as well). Among other things, this feature is useful for importing image files of maps. The picture to the left is an example of an image overlay. Photo - (Add > Photo) This is an image placed in a geographic location that you and other users can fly into and navigate. You can see examples in the Layers panel > Gallery > Gigapxl. GIS imagery - (Google Earth Pro only: File > Open) These are GIS-related files, such as .tif, .geotif, .ntf, .img, etc. The larger your image files, the more performance becomes an issue.

GPX: the GPS Exchange Format What is GPX? GPX (the GPS Exchange Format) is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet. Current Status The GPX 1.1 schema was released on August 9, 2004. GPX has been the de-facto XML standard for lightweight interchange of GPS data since the initial GPX 1.0 release in 2002. GPX is being used by dozens of software programs and Web services for GPS data exchange, mapping, and geocaching. GPX for Developers If you're a developer, read how GPX can help your application or web service. View the official GPX 1.1 Schema. Read the GPX 1.1 Documentation. Learn how to validate your GPX output. GPX is an open development effort. User Benefits of GPX If you own a GPS, find out how GPX is helping to make all your favorite applications work together. Comments To ask questions about the GPX format or propose changes, please join the GPX Developers Forum. GPX is an open standard.
[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.

How Google Earth [Really] Works Introduction After reading an article called "How Google Earth Works" on the great site HowStuffWorks.com, it became apparent that the article was more of a "how cool it is" and "here’s how to use it" than a "how Google Earth [really] works." So I thought there might be some interest, and despite some valid intellectual property concerns, here we are, explaining how at least part of Google Earth works. Anyway, the solution to discussing "How Google Earth [Really] Works" is to stick to information that has already been disclosed in various forms, especially in Google’s own patents, of which there are relatively few. For the more technically inclined, you may want to read these patents directly. 1. There are also a few more loosely related Google patents. 3. And there is this more informative technical paper from SGI (PDF) on hardware "clipmapping," which we’ll refer to later on. I’m going to stick closely to what’s been disclosed or is otherwise common technical knowledge. The Basics
