I think you can't get it. Because MODIS gives a some product(LST,NDVI.EVI..etc).The products have been produced by using multi-spectral bands ,but output is one layer.you want at least three bands to colour composite.I think you want to visualize some area as a colour map.Please use multi-spectral bands products of that area(LANDSAT,MODIS..)

As Vince pointed out in a comment - you could theoretically write code to clip a map/feature service. But that would probably be a lot of custom work. You wouldnt as much be extending the Clip and Ship tool as you'd be writing a custom extraction of JSON from map services. Generally the clip and ship work flow is comprised of 2 services: GP + Map. They both ...

I suggest to use the Overpass API, and select the admin_levels you want. Overpass API can export geojson. Note that not all countries of the world are included in full detail in OSM, but much better than Natural Earth or GADM provide. See http://wiki.openstreetmap.org/wiki/User:Wambacher#International_Administrative_Boundaries for details countrywise.

You need the boundaries of the countries, then make them in geojson format. For the data I suggest not to use OSM directly in the case you don't plan to go in bigger zoom levels, but use a global shapefile from Natural earth. For the map, you'll need Leaflet and load the file. I'd suggest to use topojson format instead of geojson. Here's the file I made some ...

it could be more than one thing, but my guess is that you're calling 'execute' and the print task is actually set up as asynchronous or 'submitJob' and its synchronous in order to tell for sure, browse the REST services directory to see what operation the service actually supports and compare that to the URL that 500s. if thats the problem, you can set ...

The European Atlas of the Seas is another great example of geoportal centered on the arctic.

I just came across Strava when looking for something similar. I've haven't tried Strava yet, but from what I can tell you can manually upload your GPS data and then map it along the lines of what you describe: You can add an activity to Strava even if you didn't record it with a GPS device. Strava lets you enter the type, time and distance for any ...

Take a look at https://osm.wno-edv-service.de/boundaries/ it contains a UI to download all know administrative boundaries from OSM in a variety of formats.

I think the application server will be doing very little so I would just go with whatever web framework you are already familiar with. You can configure GeoServer completely using their REST API and you can manipulate/query the data directly from GeoServer using WMS/WFS (preferably with JSONP) without having to touch PostGIS directly. All the application ...

You don't say how you are opening your JS script in FireFox. I believe this layer type is using Ajax calls. You cannot open the file with file://myfirstmap.html. You have to use a web server to view the map. The problem that you will face with OpenLayers is that some formats like the text/tab/csv format does not use Ajax calls. So you start with these ...

The mechanism for modifying features in OpenLayers 3, similar to OpenLayers.Control.ModifyFeature in OpenLayers 2, has been added to the trunk and is called ol.interaction.Modify. Here is an example of modifying features only. There is also a an example of combining draw and modify together, which uses an ol.FeatureOverlay, rather than ol.source.Vector, so ...

API choice is related to the scope and purpose of your project, not to mention your budget if you in fact want to use some specific functionality. The other major caveat is your web development experience, and what language you prefer or have interest in. I think the best way to answer your question is to provide a nice listing of API's available to you. ...

I use leafletjs and I think it is very simple. It is javascript based, and can draw features using various data sources. Basically, you insert the map code into a .html file and then view the file. I cannot comment on other API's, but I think that google is pretty simple, as well as Openlayers. Also, there are services like MapBox that do not require you ...

You can always try R and RShiny. You can easily create an webApp and project the results of your app into a map :D Check for more info: http://shiny.rstudio.com/gallery/superzip-example.html

I can't speak to the other platforms, but the Google Maps JavaScript API has a drawing library that lets users put lines, points and polygons on the map that you can then store wherever you choose. Check out the drawing library guide and one of the examples. Another way to get details on routes from your users is to use the Directions API (server-side) or ...

So 3 years later I finally got organised enough to learn some Rails. My initial conclusion is that Rails won't specifically help with a GIS web application - but it makes everything else so much easier. Rails handles the most common tasks and functions of a web application, meaning that the developer can just concentrate on the GIS-specific aspects, ...

If you have a one-band-dataset, it will be displayed as grayscale as default. You can change that to any kind of pseudocolour, depending on the software you use. To get real colours, you need either 3 band data with red-green-blue colour interpretation, or paletted colours.

instead of null fill, use a completely transparent fill, like this reference: https://twitter.com/derekswingley/status/487335272825094144

Sorry for taking so long to respond to this - I forgot all about it! In the end I discovered too many other limitations with the Dijit Legend widget, so ultimately I created my own, using an ajax call to the legend on the REST endpoint (.../MapServer/legend?f=pjson) to obtain the necessary info, including the symbol, which I was then able to style however I ...
