This is also called "binning", which when applied to hexagon polygons, is referred to as "hexagonal binning" or simply "hex binning". There is a top-notch blog article (Binning in GIS) at GIS Lounge on the subject, which points to an Esri blog that explains how to create the maps in ArcGIS Using a binning technique for point-based multiscale web maps ...

Matchlines are typically a feature found on plans, not maps. I'm not aware of any tool to directly implement them in ArcGIS. It's possible there are such tools in some of the mapbook extensions available out there. However there is a workaround that can roughly do it. First, you need to create a new feature class and actually draw in the matchlines where ...

(1) I have usually heard of it referred to as a "Hexagonal Map" or "Hexagonal Grid Map". Both queries turn up a lot of relevant results in Google. Example Link Here: http://anitagraser.com/2012/03/04/mapping-density-with-hexagonal-grids/ The link above also outlines the process that you would use in QGIS. If you want to do it in ArcGIS.

I like the map with a dark base layer. The representation of the overlay's is very interesting. I choose two map's with social network data's. The first map is the localisations of the tweets The second map is an extract of the game Watch Dogs with many live data's from Paris like Tweets, Instagram publications etc...

"animated map of global weather conditions" Not a map... but still really beautiful! http://earth.nullschool.net/

Thank you all for your help. Actually I'm using OL2 and GeExt, GeoExplorer functions I think the problem is that I defined in the " GeoExplorer.js "a Basemap Layer that is not compatible with my layer. new OpenLayers.Layer.WMS("Global Imagery (OpenGeo) [Online]", "http://maps.opengeo.org/geowebcache/service/wms", { ...

"Used digitally" is pretty broad, and depending on how they will be used or distributed might make a significant difference. As would the data type (vector or raster) shown in the map. For this answer, since your question title explicitly says PowerPoint and your body mentions that, that's what I'll address. The first thing to determine is whether what ...

I like to use the .emf format--it is a vector format, so you can resize without any issues with pixelation as you sometimes get with raster formats like png and jpg.

Personally, I use pdf for all maps that will be used digitally. They have the ability to be zoomed in and navigated without losing resolution. There is also a geographic element in Adobe Reader that allows you to display the different layers and information about those layers in a sidebar if needed. I don't know of any general rules, however.

No, it does not aggregate adjacent enumeration areas (polygons) into a single dot. If there's a dot to show, it's shown, and if the symbol size is too large or value count too low then the dots will simply overlap/coalesce (potentially leading to a solid polygon shape of the dot color). For areas that don't meet the minimum value, no dot is shown and the ...

Some fairly obvious things to check: 1) try replacing "localhost" with your IP address, especially if you are running your webmap off of another machine (e.g. Geoserver on guest, webmap on host); 2) verify read/write permissions for the folder containing the dataset; 3) Check the code of the openlayers preview and compare to your code. Likewise, note ...

I have never worked with Viso but my first guess was Adobe Acrobat DC Pro (former Reader Pro). There you can easily add re-, arrange images. To have more possibilities I would go with Photoshop. If you are lucky and the author of this floor plan used Illuatrator and saved the layers in the pdf you can easily import it to Illustrator and threat it like every ...

I think the best way to do this is not with digitizing or polygons, but by using the National Land Cover Database, which is a 30m resolution raster, and should look great for a whole township as you have in your post. My favorite way to obtain the NLCD for any state is through the NRCS Geospatial Data Gateway, just follow the "Order by State" link on the ...

As the comments have pointed out, you need a polygon dataset of the forested areas to symbolize in whatever manner you choose on top of the base map. You could get these by: Creating a new polygon feature class/shapefile and editing it to trace around the boundaries of forest from an imagery base map. Running a classification on an image as Aaron suggests ...

With some manual work and a Spatial Analyst extension. I assume you have access to Spatial Analyst since you are able to generate contours from DEM? I use a different approach - I show only major contours in areas with slope more that say 30 degrees but it will work the same for thinning contours with some tweaks. Create a slope raster and generalize if ...

I've always loved these cartoon maps by stephen walter (featured in a great BBC documenary series on the beauty of maps) http://www.stephenwalter.co.uk/wp/maps/. The ideas behind them was to integrate personal stories and human connections to a place into a map framework

Considering the fact that you are exporting some raster data as well; the best technique, IMHO, is to NOT use the ArcGIS PDF exporter at all but rather export to a high resolution TIFF instead and then convert the tiff using Adobe Acrobat Pro renderer to PDF. (Important note: this only works well with TIFF) You can tweak the rendering options in Adobe if ...

A layer (lyr) file is saved symbology. It does not 'get' it's information from anywhere, it is the information. At some point someone went through and symbolized each unique value in the raster to a certain color and labeled it with the LUC class. Once they had that symbology and labeling set up, they saved it out as a lyr file which allows you to load the ...

The colormap is included inside the tif file. You can query it using gdalinfo. The unique value in the attribute table should be sorted in the same order as the color map, but I would rather start from a copy of the existing lyr to create a legend instead of creating a new legend from scratch.

For those of you that may still be following this, I finally found some additional documentation on Section 508 Compliance that comes from the Centers for Medicare and Medicaid Services. I would say this is a good follow-up to the above post from @jwd630. Making Documents Section 508 Compliant
