I've create a geodatabase with about 100 feature classes for my home province. I want to be able to specify a project extent and clip the feature classes to that extent and save into a new geodatabase. I managed to do this in ModelBuilder using an iterator function with one problem, a new...

This is the sort of map made astonishingly simple with GIS and the nationwide datasets now available. I labeled the towns and highways manually; the smoothed I-25 was borrowed from my North American basemap. I see I should have spent a few minutes getting rid of kinks in the mountain-area...

I was wondering if there is a easy way to show that the spheric Mercator projection is conformal? Its construction from a point light source is quite intuitive. One can also verify that the projected graticule has meridians and parallels meet at right angles. But how to show it preserves any...

I have js file like this and I have saved the ClusterLayer.js in all directories like root --> ClusterLayer.jsroot --> extras/ClusterLayer.jsroot -->js/extras/ClusterLayer.jsroot -->js/ClusterLayer.jsand the file is like require([ "esri/map", "dojo/_base/array"...

ArcScene includes the capacity to animate 3D text added to the scene, through the use of Graphics Layers. I'm able to use this to make text fade in and out as visibility of layers is changed, however I'd like to achieve something similar in ArcMap. I've got a clunky work around which involves...

I read about Determining North-South Line Via Watch Method recently (page 9). What is the underlying geometric/celestial reason this works? What is the error to true north given this method? Is there a more accurate method using a watch and the sun? What about the moon? أكثر...

QGIS 2.10.1. I have read that it is "impossible to make the legend smaller then its contents". Is there a way to set the legend to shrink the font size when re-sizing the bounding box? Or when you add a new item to the legend? From my reading of answers to related questions I suspect not. (I am...

I have a point shapefile and a grid shapefile and want to do interpolation so that each of grids has it own value which is followed by the point shapefiles, also I want to add a polygon shapefile as the mask. أكثر...

I have migrated an classic COM ArcMap Extension of mine to an add-in.I have tried the new persistence approach of add-in's but I cannot serialize my custom objects through the XMLSerializer. I get all sorts of COM errors. The custom objects all implement IPersistVariant. And I suspect this...

I have built and maintain a SWTOR game map atlas. At the moment, it's all static jpg maps, but I would like to get the info into an actual GIS software to get more functionality and make my website more mobile-friendly. I assume the first step is to get the game map into a GIS software. I have...

I am using ArcGIS 10.2 for desktop and will be using point and click to digitise a cycle network shapefile and network data sets then use model builder or python. Before I begin I was wanting to check my plan to see if I am missing anything or doing it in the wrong order. My aim is to assess the...

This is my first maplift map, I'm hoping to add a few more but since this is where I live and work I have easy access to a lot of data and was able to do this on my lunch break. https://www.dropbox.com/s/xqrt5o9j4zjea8l/UnionCountyMap.png?dl=0 I was wondering what other maplifters/carto...

I am looking for a way to create isometric 3D maps based on data stored in a PostGIS database. My idea is to create a PostGIS function that will return a SVG image like the one below. It is easy to do for a 2D image using ST_AsSVG and some math to position the map, but I don't know how to...

I'm writing a project for school and as a part of the project I need to tell if a certain point is within a given region (which is a polygon made of lat, lng tuples). So far I was working with http://www.doogal.co.uk/polylines.php but unfortunately this isn't enough when I want to draw 50...
