The WMS standard allows the client to request an arbitrary region. If the client wants tiles, it can makes its requests in a tiled pattern, but the server has no way to know that's what's happening and if the server stores the map as tiles of its own, it has no way to let the client know what the tile arrangement is. There are two ways to deal with this. ...

I've figured out how to use their web services. It looks like you have to send the token as a header instead of directly in the URL. For example, you can download an add-on to your browser such as postman that allows you to send GET and POST requests to web servers. Then select the option to send a get request to the web server such as https://www....

If you use QGIS, you have at least two options to publish your maps without dealing with a server: install qgis2web-Plugin and generate web-maps with openlayers or leaflet: - you can upload the output to a webspace (if you have one) and your web-map is there. However, export tries to "translate" your QGIS-project as good as possible to openlayers/leaflet, ...

Finally I found the service best shoot my need, Here MAP API. They support mulitiple language and has good zh-hant/zh-hans matching; eventhough, they don't have compelete translate, but well matched, better then Google Map Serivce. Update Google map is still the best one; during my using the HERE MAP API, I found a lot of cities are missmatched in Chinese ("...

Unfortunately no. As Alex said, there is no real link between the original published mxd and the service (although there was in previous versions). You can however find a copy of the published mxd on your server in your ArcGIS Server directory at %arcgisserver root%\directories\arcgissystem\arcgisinput\%service folder name%\%service name%.MapServer\extracted\...

Landsat is now available via Amazon Web Services Landsat 8 data is available for anyone to use via Amazon S3. All Landsat 8 scenes from 2015 are available along with a selection of cloud-free scenes from 2013 and 2014. All new Landsat 8 scenes are made available each day, often within hours of production. http://aws.amazon.com/public-data-sets/...

Update: Nowadays I prefer Plunker for this, primarily because it allows you to create any number of files. This lets you create more realistically sized/organized demo apps, rather than stuffing everything into one HTML/JS/CSS file. Here's a nice Leaflet example: http://plnkr.co/edit/Y9uk2G?p=info I have found JSBin and JSFiddle to be extremely useful in ...

A slight update a few years down the line, since I'm looking for the same thing: The ESRI link above no longer works, but gives the option of proceeding to http://route.arcgis.com. Under the API documentation there is a price list, where a "simple route" currently costs $0.004 per route. Could not locate a free option. HERE maps would appear to have 250K ...

The problem in this case was rather stupid:) The cache mentioned above was residing in a folder, that was located in another folder, that was located in another folder. So despite the fact that I registered the main folder as a cache folder for the server, it couldn't read inside all these folders. So we created a new folder, named it exactly as the map ...

The response is obviously yes and there is probably a bunch of good solutions. Picking a favorite one with Geoserver, for example: create a sql function with "location point" as parameters witch returns 5 rows (nearest schools) using order by st_distance and limit 5 create a geoserver sql view and use your above pg function; Use WFS queries;

There are a few options: Latitude / Longitude to ZIP + 4, allows you to input the lat, long and receive a Zip code in return. You could also use this to input the values and run the search yourself All US zip codes with their corresponding latitude and longitude coordinates. Comma delimited for your database

The JSON returned from that URL does not look like it conforms to any standard format. Any system that could map from that URL would have to know it was an array, with an array of "weatherStations" and each of those elements had an array of "sensorValues" and in each of those is eventually a measurement and a description of what that measurement meant. ...

Consider to use GRASS GIS 7 for this. While it yet officially released it is much faster and also offers http://grasswiki.osgeo.org/wiki/WPS support. Ourselves, we use it to process raster and vector data on a cluster in the multi-terabyte range. See also http://grasswiki.osgeo.org/wiki/Category:Massive_data_analysis

According to the documentation, the token must go in the header, not the url: An example using curl: curl -H "token:<token>" url An example using jQuery: $.ajax({ url:<url>, data:{<data>}, headers:{ token:<token> } }) Example url: http://www.ncdc.noaa.gov/cdo-web/api/v2/data?datasetid=GHCND&locationid=ZIP:28801&...

Let's start with some assumptions: You really need 5000 web requests per second, and It would be possible to service those requests in only 5 seconds, and The queries could be serviced by exactly one CPU core, and Each core only needs 4GB of RAM, and The optimal core to CPU chassis distribution is 32, and Each CPU chasis has enough SSD disk to service all ...

Add all your imagery to one Map Document. ( I have used Mosaic Datasets in this image - but there will be no difference in how your imagery acts in this process) Share your Map Document to your Server via File>Share As>Service. Setup all the requirements in terms of name, location, settings and cache. - Wait for the cache to complete and then navigate to ...

The error message is misleading when it gives a hint about using for ignoring the error. The essential information is in this message HTTP status code: 0, error: SSL certificate problem: self signed certificate in certificate chain. You can read more about certificate chains from the net, for example at https://msdn.microsoft.com/en-us/library/windows/...

There is no way to configure the workspace on a per-layer basis, it will end up in the same workspace of the store it comes from. So, to change the workspace of a layer, you'll have to change the workspace of its store. That will also move all other layers coming from the same store, mind.

Did you save the corresponding R object as well? E.g.: # Download and save map image and R object library(ggmap) egy.map <- get_map(location=c(lon=30, lat=26), zoom=6, maptype="terrain", filename="~/Desktop/ggmapTemp") save(egy.map, file="~/Desktop/egy-map.rda") # Restart R or RStudio before running the code below library(ggmap) load("~/Desktop/egy-map....

Most companies actually seem to use dual range address calculators (At least in my experience the results are consistent with that behavior). Basically each uninterrupted strip of road has a range, or multiple ranges of numbers, on either side that specify the maximum street number and minimum street number. One side has odd and the other usually has even. ...

You have a couple of options: For an R-based solution, see the AQP family of packages, in particular "soilDB" The "soil data access" website 2 provides a limited SQL interface to the SSURGO tabular data. The SDA_query() function from the soilDB R package provides a simple interface to this web service. There is a couple of tutorials 3 on the topic at the ...

At work we did a project for a customer that needed millions of polygons. It was other requirements that pushed us to CartoDB, but it handled millions of polygons fine. The customer is hosting their own instance of CartoDB because the amount of data they're using made CartoDB's plans too expensive. That said, self hosted CartoDB setup is a real pain, so ...

OSRM has an routing API that can do that. You can find the documentation for the API here. But you have to put them in the order of appearance beforehand. To route via certain coordinates list them in the query string in the order of appearance (currently limited to 25 max points and to vehicle routing only): http://router.project-osrm.org/viaroute?loc=...

I'd really recommend against parsing the output messages. For one, it'll be tedious. And more importantly, 2, you have INFO level messages on. INFO level displays path information to resources on the Server machine. Many people would consider this a security risk (leaving this level of information available to anyone consuming a service) So here's some ...

Yes, you can definitely use USGS National map ortho-imagery to extract features, using heads-up digitizing methods (HUD.) The trick here is to work within a projected environment using UTM or State Plane as a coordinate system to ensure fidelity. Another consideration should be the age of the image. Ensure you are working with the most current image possible ...

Unless I am misunderstanding something, the situation shouldn't be that complicated. Create a number of web maps which all refer to the same datasets that are stored in ArcGIS Online. Give edit permissions to the staff, and allow them to make changes. Something like this: These changes will automatically be seen in all webmaps which refer to those ArcGIS ...

This will depend if the Service producer has enabled KML, but will be the easiest way to get a KML format of the service. From here, you can add the content to your google map with no problems. Navigate to the ArcGIS Service Directory of the address you have (I will be using a sample ESRI server) https://sampleserver1.arcgisonline.com/ArcGIS/rest/...
