First, let me outline the two steps from the location on the physical Earth's surface to the projected (plane) coordinates since they are slightly different from what you described above: From the physical location on Earth to the mathematical reference surface: when you capture coordinates with a GPS receiver, you get the ellipsoidal coordinates (lat, ...

Why do you need 800 separate MXDs? You can make a map for each of the 800 polygons in a single MXD using data driven pages (DDP) simply by setting the layer with 800 polygons as your index layer. Then, DDP will iterate over each feature in that layer and export a map in whatever format you want. Check out the help file here: ...

I googled a bit and found this: "To resolve, go to the 'Layout' toolbar and select the 'Change Layout', select one of the templates" Have you tried it?

In order to interpolate prices with kriging you first need to convert your geographic coordinates to projected coordinates. Assuming you have them, below there is a reproducible example, showing a way to accomplish such task. library(sp) #Spatial data containing variables which can be interpolated. #We will use the zinc column; as an equivalent for ...

To start off, a rectangle in GeoJSON needs five coordinates: the four corners, and the last one duplicating the first, to close the polygon (this is a common convention for many spatial formats) - in your example, you only have two. Secondly, the coordinates property in the geometry should be an array, not a string, like this: ...

To address your second question, I can say, that depends on how you project earth topography on your ellipsoid (how the straight line is defined). The straight line can be rhumb-line, a line vertical to the ellipsoid surface or a line that passes through the ellipsoid center. If you define this line, then you can say any LatLong on this line are equal. ...

I think that this toggle map view tutorial from CartoDB is exactly what you want to achieve: http://docs.cartodb.com/tutorials/toggle_map_view.html In this case, instead of dates they're using another information, but you just have to edit the SQL queries conveniently depending on your case.

You could try using bookmarks. It would zoom to a specific extent at a specific location. You would just have to enter the extent, save the bookmark, and click back to that bookmark whenever the user is choosing that extent.

Try exporting individual layers to ai (or group of layers). This way you can detect which layer is causing the whole map not to be exported as a vector. In doing so, I found out 3D character marker symbols was causing the problem.

Go to ArcToolbox > Cartographic Refinement > Set Representation Control Point At Intersect tool, and run the function on your feature data (after you created a representation for it.) The tool aligns the hash boundary symbology so that when it overlaps it does not look like a solid line.

Besides CartoDB, the OpenStreetMap community made a few tools for making a video out of a set of GPS tracks. The original on was "Party Render" which will produce a video like this one for example. It's a bunch of old python scripts. Since then we've seen a been a bunch of Party render#Alternatives We used to use GPS a lot during "Mapping Parties" (These ...

You would do this by creating a new data frame. In the new frame you would have your large map, and in the smaller data frame your more zoomed in map. For ARC Quoted from ESRI: http://mappingcenter.esri.com/index.cfm?fa=ask.answers&q=881 Here is how you can create an inset map in ArcGIS: In Layout View, insert a new data frame and rename it Inset ...

Torque is not capable of moving polygons at this point, but with CartoDB.js you can make these temporal changes to happen. I always like two show two different approaches: 1: Reloading the layer by applying a new CartoCSS - My example available here is a big simplification, but you can have several CartoCSS codes prepared for different times and apply them ...

The proper solution to this is using Symbol Levels as explain in this post How do I make line symbols intersect cleanly without showing edges in QGIS?

Very nice answer by @AndreJ which should get you the nicest results. An alternative is to change the Cap style of your blue line to Flat. This should get rid of most of those segmented appearences (tested on the .kml file you linked to): Without Flat cap style: With Flat cap style Hope this helps!

The simple reason for the interruptions is that the casing is along the line, and around the ends too. In QGIS , there is a possibility to draw lnes with no end cap, but the street casing would stop at the connecting point, and not at the casing of the other road. The line may be interrupted in the source file, because the street name changes, or what else. ...

I used 10-m lake shapefile data from Natural Earth along with country borders from rworldmap to reproduce what I guess you were trying to achieve. Hadley Wickham wrote a nice tutorial on how to visualize spatial data using ggplot2 and I strongly encourage you to have a look at it. Still, a short workaround is required in order to get the visualization to ...

In Layer Properties > Style, there should be an Advanced button which has the option Symbol Levels. Here you can define which symbol should have higher priority when displayed. Note that I used QGIS 2.8.2-Wien to find this option so there should be something very similar for QGIS 2.10.

are you tried for invert the symbol? so lowest will be on top and highest will be on bottom

Some visual examples. As @ako suggested, dotted overlay might be used to represent significance. Example from Nagy, C., et al. (2014). Hierarchical spatio-temporal mapping of premature mortality due to alcoholic liver disease in Hungary, 2005-2010. European Journal of Public Health, 24(5), 827–33 (link, paywall): Somehow opposite method, that blurs away ...

I think your question makes no sense or is unclear. You do not state why you want to put your home adress/ name in Google Maps. Don't think that there is a attribute for "Home of sudip mondal". Google Maps are not the yellow pages. Only "relevant" information like businesses, doctors etc. are shown there. If you have a business use the Google Maps Map ...

Yes, cluster layer is right here, https://github.com/Esri/cluster-layer-js or a more robust one here, https://github.com/odoe/esri-clusterfeaturelayer

If you want to emphasize areas where the old people live, only display their dots. Mayne use a setup with layers for different age groups or a small multiples approach. If you want to show a ratio, for example "this place has more old than young people", use any kind of choropleth map. Hexbinning or another kind of same shapes is one way, if you want to use ...

Your code looks correct and the marker is visible, however, you will need to zoom out a little bit to see it since the marker you dropped is too close to the north pole (see image below): I tested your on jsfiddle and I am able to see the marker by changing the default zoom level from 3 to 0.

try hex binning. https://github.com/minus34/postgis-scripts/tree/master/hex-grid here is some code for creating hex grids over Australia at varying levels put together by @Minus34. It's very useful for being able to show the large amount of point data into useful and spatially identical areas.

Since I dont know which of these two you meant, To make the actual layout view map larger on your screen use your mousewheel (also right click and zoom to whole page, but this may not zoom in as much as you want.) Or use the layout toolbar and the layout zoom tools... To make the map fit the actual extent of the page right click on the map, then ...
