Doing a snow removal project within a county figuring out the fastest route for them to traverse on the roads to remove the snow from the sidewalk I was able to find the roads/street shapefile for the county and using network analysis route analysis I was able to find the shortest distance for...

I have an ArcEngine 10.1 app. It has been running fine. It opens an .mxd on initialization. The .mxd contains 3 feature classes that have class extensions applied. I just tried to make a change to the app for the first time in years and now I cannot get the app to load the .mxd. The .mxd can...

I need to close popups on an object, but I don't know whether it is a layer or a geoJSON (and hence a feature group). If the former, I can do layer.closePopup(), but if the latter, I have to do layer.eachLayer().closePopup() (I think). How do I test whether an object in Leaflet is a layer or a...

Respected All. I have simulated LULC of my study area for 2031 based on the 1990-2005 and 2005-2015 LULC maps. I also prepared LST maps for May-1990 and May-2015 using LANDSAT-5 and LANSAT-8 DATA. Now I want to simulate LST for 2031 using 2015 LST map. How can I do that. I need your help in this...

StreetMap Premium for ArcGIS is a ready-to-use dataset for map display, geocoding, and routing. It’s been around for years in the file geodatabase format, and for use in Desktop and Server. Recent advancements in Desktop (ArcGIS Pro) include a map display symbology for faster drawing times...

I am attempting to cast a MultiLineString feature in WGS84 to UTM33N using RGeo. Unfortunately, RGeo::Feature.cast, instead of casting the feature to the desired projection, returns the original feature unchanged, as the checks at the end show. Why does the conversion result like this? What...

We have a geometric network with sewer pipes that have their flow direction based on digitized direction. Some of the pipes, however, have indeterminate flow. We would like to find all the pipes that have indeterminate flow. We can do this by setting the flow direction arrows and identifying...

Bit of a challenge here which I've been grappling with for some time. I'll explain my full work flow so you can reproduce if needed. I'm creating virtual landscapes in Google SketchUp which I ultimately would like to use in Netlogo to examine how turtles interact with them. My problem is...

I'm trying to solve a route using an impedance of miles (to get the shortest route) through ArcGIS Sever 10.3.1 rest API. However, I would also like to get the travel time of this route based on historical traffic data for a specific date/time. It seems like ArcGIS only supports historical...

Bonjour, Je cherche à réaliser une sélection par attribut, où je souhaite sélectionner plusieurs attributs d'une même colonne. Je travaille sur des fichiers d'inventaire ornithologique, donc par exemple, j'aimerais sélectionner toutes les lignes de ma table dont la colonne "Nom_espece"...

New maps of Ceres were released today at the European Planetary Science Conference in Nantes, France. One is a colour-coded topopgraphical map that resembles a map we saw earlier but adds newly approved names for topographical features. Another, the false-colour map seen above, combines imagery...

I have an ArcGIS Javascript Map Application that uses the Print task to export the map to a PDF. I have given the users the ability to add graphics to the map, such as points or polygons, along with the ability to add a TextSymbol graphic in order to customize the PDF map output. The problem I...

I am trying to join multiple polyline attributes that intersect with a buffer polygon. In the picture below you can see buffers i have created which are actually intersection buffers. Around it are the poly-lines which are streets with information about traffic volumes. I want to add all the...

I am trying to print a map like the image below. And I have a problem with grid and graticule.I understand that the best way to have a grid (in UTM, meters) and a graticule (in GMS) is by adding both grids and changin the SRC to each one. The problem with this method is that I can't find an...

I need to reclassify some raster data which was made from Inverse distance weight from points.So after getting the Inverse distances weight, I tried to run reclassify, but got: Error 999999: Error executing function, The table name is invalid. Failed to execute (Reclassify).I tried to chosen...

I am working on elevation data for an area in Sudan. Between Google Earth Pro and SRTM elevation data, which one is more reliable? أكثر...

I have some code that will take a ArcGIS 10.2.2 feature class and post a copy of it in a different geodatbase. My code is set up so the end user can pick the feature class they want the model to run (getparameterastext). My problem is the code doesn't name the new feature class the same name...

Using ArcView 9.I have a data set of about ten thousand parcel polygons and a similar number of driveway polygons extending from a roadway polygon into the parcel polygons. My ultimate goal is to get the driveway area within each parcel. Ideally this could be done through the creation of a new...

I checked on this site Heron Map Examples, I found very exciting apps then tried a couple of them out locally on my computer. What I did is I copied all the source code then arranged links properly, the only problem I'm facing is to get the getFeatureInformation working.It only says "No Feature...

By Barbara Pualani Any household organic material can be composted (and used again!). Earth-friendly urban dwellers know just how precarious composting in the city can be. Storage bags of frozen food waste in the freezer, the subway ride overloaded with multiple bags, sometimes...
