I have one simple question what are the main differences between Synergis Weboffice and Geocortex Essentials? I know they are both used for creating web-based mapping application for end users and they depend on ArcGIS server for working but are there any differences between the tools and...

I'm trying to iterate through a GeoJSON file (below) and eventually populate an array with a few attributes within "properties". I keep coming up short working through various examples I can find. Do I need to embed another $.each() to get to properties. If it isn't obvious I'm new to this and...

ArcGIS 10.2 can address 64-bit memory space which means not only can it use far more of your available RAM but this new change also allows ArcGIS 10.2 to use all the cores you have available on your CPU. I have 8 cores on my workstation and we are going to try putting all of ... أكثر...

Does anybody know where there might be some good/current FEMA data? I am interested specifically in the LOMA data for Florida. I have found a WMS Service that is hosted by FEMA but I'm having trouble actually bringing it into ArcMap. أكثر...

I have an address point Feature Class that has an addressID field. I am trying to write a trigger that will in effect auto increment this field when a new address is added to the map. I cannot alter the table and I cannot rely on users to populate this field when they edit. So far, I have...

I am outputting a shapefile from an intersection, and adding to it the columns “intersec_area” and “percent_area”. I have intersec_area working but I want to calculate percent_area by taking intersec_area, multiplying it by 100 and dividing by the column in the table named “AREA” (e.g...

I'm interested if anyone have idea how to automatically create (maybe in R?) dynamic grid of polygons with specified approx. area (for example around 20000 m2) based raster data or points with values and locations. I'm attaching image of what I'm looking for. This map is created manually but...

I would like to merge divided roads from openstreetmap, and a tool that keeps getting mentioned is Skeletron, for example here. I tried the tool on a small geographic area, and the results are fairly poor. I used zoom 18 as input, and received this: Based on the documentation, and the linked...

Smell is important yet the most unappreciated*sense. *It is the only sense which is almost impossible to imitate by technology. Look at our smartphones. They see, they hear, they sense our touch but they don’t recognise odours, and I don’t expect them to do it anytime soon. A group of...

Working with geographic data typically implies the use of some software. At the beginning of the GIS age, from the 1980s on, the “blockbusters” of geographic software production such as ESRI, ERDAS and MapInfo were the first to realize the concept of splitting spatial and attribute information...

This similar, but not quite the same as this question. I need to pick, regardless of distance, the closest 'n' points to a given point in another table, using postGIS. Imagine a table with city names, state names, and a centroid for the city itself, and another table with point information on...

I have a shapefile with OSM data (road networks) for an entire state. When viewing the entire state, or even down to the county level, the display performance is painfully slow. How can I simplify the roads features (remove vertices, removes bends, remove points)? My preference is to perform...
