Cartography on the Web Map Servers[Maps] [Software] [Photos] Google Maps This is my default mapping program, with an amazingly fast user interface which lets you drag the map with your mouse. Here is where I work. U.S. The USGS covers many topics in geology, mapping, and water resources. The National Map is an interactive display of the entire country as a topographic map, with variable overlays. Maps are accessible through the Digital Elevation Map index The University of New Hampshire has 1903 USGS maps of New England on line. The University of Iowa serves 1:24000 and 1:100000 maps of Iowa. TopoZone has adjustable-scale USGS topographic maps for the entire United States online. Map Machine An interactive online atlas based on the National Geographic Society Atlas of the World. Earth Maps(tm) DeLorme Mapping provides street-level maps and trip routing for any location in the US, with a simple interface and faster response time than their competitors.

How to Format your Data for Tableau Public For those of you who maybe didn't work with data too much before using Tableau Public (I fall into this camp), understanding how to format data can seem daunting at first. Once you play with it a few times though, it becomes pretty easy. We want to make that learning process even easier, so we're starting a three-part video series introducing how to format your data for the best results in Tableau Public. Start your data in cell A1Have the first row be the column headersHave every subsequent row be one piece of data This video takes a look at the first suggestion: starting your data in cell A1. As mentioned in this video, it's important to start your data right away in cell A1, and also get rid of anything that isn't actually data. We'll have the next video on column headers out soon, so sit tight! Feel free to leave us a comment and let us know what you think, or how we can help make Tableau Public even easier to use.
Alpage ALPAGE (diachronic analysis of the Paris urban area: a geomatic approach) is a research program coordinated by Hélène Noizet (LAMOP), which is supported by the ANR. Based on the association of 4 laboratories, and collaboration of many partners, it brings together some twenty researchers or academics in humanities, social sciences and communication studies. These historians, geomaticians and computer scientists are building a geographic information system (GIS) about the pre-industrial Parisian area. The concluding symposium, held on 7 and 8 june 2010, ended the first phase of this program (scheduled for release in January 2013). Beyond 2011, the work is going on thanks to masters degree students and to the support of CNRS, with the TGE ADONIS. Production work data, which benefited until June 2011 supported by the CNRS, continues through individual research specific to individual researchers or students, allowing regular updating of the mapping platform.
How to draw a map This tutorial covers my entire process for how to draw a map – from start to finish. In this case I’m illustrating a simple town map, but the steps apply to any map. Tools and Software I used Photoshop for this map, but all of this can be done in Gimp (for free). I also use a graphics tablet. Tablets are great for this work, and if you’re thinking about digital map making I’d recommend picking one up. I’ve uploaded the full photoshop file if you want to look at the final file and see how the sausage was made. Outline of how to draw a map My steps in drawing a map are pretty consistent: sketch an outlineink in the outlinesadd detail linesblock in dark areasadd overall light and shadelay in base coloursadd detailed light and shadelabelfinal polish – border, colour balancing, tone balancing I’ll go through each of these steps in order. Setup To begin, let’s open a new document. I grabbed one of my parchment textures and set it as the background. Sketch the base for your map Ink the Outlines
Blog, CartoDB makes D3 maps a breeze Anybody who loves maps and data can’t help but notice all the beautiful visualizations people are making with D3 right now. Huge thanks to Mike Bostock for such a cool technology. We have done a lot of client-side rendering expirements over the past year or so and have to say, D3 is totally awesome. This is why we felt it might be helpful to show you how easy it is to use D3 with CartoDB. In the near future, we’ll be adding a few tutorials for D3 to our developer pages, but for now, let’s have a look. Creating your first map Using CartoDB’s SQL API, you can load GeoJSON straight from your CartoDB table into your D3 application. Paired with d3.geo, you can quickly develop maps. TopoJSON support We are actively working on supporting TopoJSON in CartoDB and when deployed, this will open the door to even faster D3 maps. Client-side simplification Many of you have probably seen some of the cool client-side simplification work that is being done.
13 Tips for the Best Nap Ever A mid-afternoon nap of just 10 minutes can help you stay alert for more than two hours when you’re sleep deprived, according to research from the journal Sleep. But it’s not just insomniacs who benefit from some midday zzz’s. Napping can also improve alertness, performance, creativity and provide a slew of other benefits among the well-rested and yawning masses alike, says psychology professor and nap researcher Dr. Sara Mednick, PhD, in her book Take a Nap! So how can you harness the power of the restorative nap? Read on for our expert-approved tips for the perfect snooze. When to Nap There’s a time and a place for playing catch-up, and while some strategies are universal, others will depend a bit more on your individual lifestyle. “A 30-minute nap has been shown to improve alertness and prevent unsafe driving nearly as well as coffee, according to one study.” 1. 2. 3. 4. 5. Nap Smarter So how do you make the most of your precious nap-time minutes? 6. 7. 8. 9. 10. Who Shouldn’t Nap 11. 12.
Gridded Population of the World - GPW v3 Introduction Note: "Gridded Population of the World, v4" is now available and supersedes GPWv3. GPWv4 provides gridded population estimates with an output resolution of 30 arc-seconds (approximately 1 km at the equator) for the years 2000, 2005, 2010, 2015, and 2020 based on the results of the 2010 round of censuses, which occurred between 2005 and 2014. GPWv3 depicts the distribution of human population across the globe. Population data estimates are provided for 1990, 1995, and 2000, and projected (in 2004, when GPWv3 was released) to 2005, 2010, and 2015.
[R] Faire des anamorphoses cartographiques avec Getcartr – Carnet (neo)cartographique Comment faire des cartogrammes avec R ? Aujourd’hui, c’est possible grâce aux récents développements de Chris Brunsdon de l’université de Maynooth (Irlande) qui a réalisé un front office (Getcartr) permettant d’utiliser simplement et efficacement le package Rcartogram. La méthode d’anamorphose proposée par ce package est basée directement sur le code C développé par Mark Newman (cart). Cette méthode, conçue conjointement avec Michael Gastner, repose sur le processus physique de la diffusion de la chaleur (diffusion linéaire). Référence : A Diffusion-based method for producing density equalizing maps, Michael T. Installation L’installation s’effectue en deux temps. 1) Télécharger et installer le package Rcartogram. 2) Installer le package Getcartr Dans R, tapez la ligne suivante pour télécharger et installer package Getcartr développé par Chris Brunsdon : library(devtools);install_github('chrisbrunsdon/getcartr',subdir='getcartr') Utilisation
