I assume you are trying to convert your scripts so that they can be used in open source software or with open source libraries, otherwise the question's title would not make too much sense to me. First of all you have to be aware that arcpy.AddMessage solely makes sense in one specific context: when used in a script tool that is used within ArcGIS. It does ...

You can also install Cartoview take a look at Cartoserver. Cartoserver will provide you some basic ESRI JSON support to get yourself started with ESRI REST API for free before you buy the full version. Geoprocessing is not supported, however if you will have a high entry point to your solution

We've been building a web based version of Collector for ArcGIS. Not tied solely to ArcGIS Online it works against ArcGIS Server and Portal too: http://www.webmapsolutions.com/disconnectedjs-for-arcgis We have used the ArcGIS Javascript API. But there is no reason this approach would not work in a more generic (OGC) way. The library we have built simply ...

Both ArcGIS and QGIS would do the trick (assume you have got a csv spreadsheet in hand): ArcGIS version: Use 'Add data' to add load your csv file onto ArcMAP; Right click the csv table choose 'Display XY', and set the right position field. Right click the new .event layer, export it to a shapefile (now you will have a point layer you can work with). if ...

I coded the sinusoidal intercepted projection in javascript, so it runs in web browser. You can check it here: http://www.winski.net/?page_id=12 You only need to pick your input image, sinusoidal intercepted projection from list of projections, number of gores, and click "project". It is under BSD, so feel free to do anything you want with it :)

Openlayers should fit your need, but I don't know what kind of "gis files" you want to deal with. Consuming and displaying 256x256px tiles is easy, but storing a whole country offline will slow down any application.

After a day of struggling with GDAL, I can confirm the methodology works and runs quickly. I was working with ice chart E00 files from CIS which I had converted to arcinfo coverage using avcimport. I have posted my prototype code below to help others. The E00 was converted to an arcinfo coverage called "test". The script must be run from the same directory ...

There is a new option as well, which is www.aequilibrae.com, working as a plugin for QGIS (I need to disclose that I am the developer of it). It much less powerfull than TRANUS, but it is completely written in python and cython.

Admitted not the simplest one to learn, but nobody (except one in a list-answer) citing GRASS ? I like its very simplicity when commands are given as simple bash scripts.. and I like to use bash scripts in order to keep track of what I do.. (and GRASS even does it automatically if you still want to use the GUI, as it keeps the log of the commands in a ...

Also, check LAStools: http://www.cs.unc.edu/~isenburg/lastools/ for rapid and clean processing of lidar data. This link will show you how lastools can be used in a workflow for tree crown calculations: http://rapidlasso.com/2014/10/23/discriminating-vegetation-from-buildings/

A literature search would provide you a wealth of information! Bob McGaughey with USFW-PNW in Seattle, is the developer of FUSION and I am sure would hand over the source code for watershed segmentation. Randy Wynne is at Virgina Tech and developed an IDL virtual machine program implementing a variable window filtering approach Popescu & Wynne (2004). ...

Since this is being liked to by duplicate questions I'll add my own two cents with some more free and open-source tools. First, for command-line/batch processing: libLAS (www.liblas.org): reads, queries, and translates .las files, as well as doing simple transformation operations (bounding box cropping, decimation, intensity and classification filtering, ...
