After burning for almost a month, this wildfire complex in northwest California was 65 percent contained. أكثر...

I want to calculate the average value of a raster file within each polygon boundary of my shapefile. Because I want to preserve area I wish to use the Goode Homolosine (Land) projection. The original shapefile has a geographic coordinate system WGS1984, and the original raster file is also in...

Summary: Trends in pesticide concentrations in 38 major rivers in the U.S. during 1992-2010 reflect large-scale trends in pesticide use and regulatory changes, according to a new study by the U.S. Geological Survey.&nbsp Contact Information: Karen Ryberg...

Community leaders and EPA presenters By Amanda Kaufman I have seen a fast expansion of next generation air pollution sensor technologies while working in the field of citizen science for the past three years. Small, hand-held air quality sensors are now commercially available and provide...

I made a map with a search box that is related to a country. Entering a postal code will zoom completly in to the asked postal code. I would like to center the map to this asked postal code, but not to zoom further in. I saw several example maps with a maxZoom. Therefore I tried to set maxZoom...

I'm investigating solutions for a business-intelligence-like system, and am finding it time consuming to find out the specific advantages Geocortex has, that others do not. What does essentials provide specifically for security that ArcGIS server api does not? Also, is there a list of features...

I have thought about using ArcGIS to create a raster map of latitude/longitude (0 to 360 degrees) temperature data (in Excel format). This temperature data reflects the total amount of warming that has occurred per degree Celsius of global warming by location. My data collection process involves...

To get started, head over to openstreetmap.org . There to can create an account, and start making map changes and edits right away. Good luck! أكثر...

I'm new to remote sensing and am trying to get my head around it all so apologies in advance for the noob questions. I've been playing around on envi and have produced some NDVI and LAI images- they look exactly the same but the value ranges are different what is the reason for this...

I'm simply trying to loop through the first immediate set of folders in a directory, then the GDB's, and finally the feature classes. I've seen examples of arcpy.da.walk and os.walk but it ends up going through every file but never sees the feature classes. import arcpyimport osrootdir =...

At this time, I'm able to create a relation (1:M) between two table or geometries. After, I user Identify tool to exploit the relation. It is only possible to use this feature when your Identify tool is done on one (1) geometry. Here my question:Is it possible to select multiple geometries in...

I have a geotiff image that rings in at about 290MB. However, once I smooth it using a gaussian filter I'm unable to get it back to that size, it ends up being 1720MB. The size isn't really the problem so to speak, it's that when I go to use gdal_contour it takes 200x as long to contour the...

Google's Map Maker is in the process of reopening, with six countries reopening on August 10 and another 45 countries last Monday. Map Maker, Google's tool allowing users to make changes to Google Maps, was suspended last May after some embarrassing edits came to light. Regional leads are now in...

I'm creating a web map in ArcGIS Online that references a MapService from our internal server, which also has feature access enabled (FeatureService) for editing. When I add the map to Web AppBuilder I get duplicate layers in the Layer List (one for each layer individually, plus the "group"...

I have come across a problem I am very puzzled about. I am working with two polygon shape files, one of which is a buffer around the other, and a point shape file in a project set to EPSG:54016. All layers are correctly reprojected and in the same CRS, OTF is turned off. I am now trying to...

Can you please let me know if it is possible to bind our custom DOM into the geometry point instead of ArcGIS API SimpleMarkerSymbol()? I tried to do this like below but it is not doing the job! var point = new Point(-126.687482, 54.793577); var pointSymbol = ' '; var pointAttributes = {city...

We have a lot of polygons(some of them contain holes) and there are also a lot of points inside different polygon, these data are processed as ESRI geodatabase format. Now we have to do some spatial and property search in our JavaEE application which use the Oracle 11g as the database, for...

Although Colombia is not usually classified as a major oil-producer, it ranks 19th in the world according to the Wikipedia, turning out more than a million barrels a day in late 2014. Although this figure was well below that of Venezuela (2.5 million barrels a day), it surpassed those of such...
