OpenWebGIS is online Geographic Information System

Mathematical operations in OpenWebGIS - on the attributes of map layers
openwebgis

In the description of geographic information system OpenWebGIS there is often a phrase:
"In OpenWebGIS you can use the extensive mathematical functionality to calculate and analyze your data."
It is written because OpenWebGIS has a large set of such functions, among them there are geomathematics functions and mathematical operations on the attributes of map layers. OpenWebGIS (only in the online version) has a large set of geomathematics functions (functions as WPS, provided by Geoserver, and work with them is automated by OpenWebGIS).

Source code of OpenWeGIS for Android on GitHub
openwebgis
Recently the new opportunity has appeared for OpenWebGIS users to download source code for desktop Windows&Linux operating system from GitHub. Please read more about it in the article "Source code of OpenWeGIS on GitHub. Initial commit."
Later the new version of OpenWebGIS for Android operating system was created. You can read about it in details in this article "The OpenWebGIS now as Android app". Ready to use Android apk file for your mobile devices is available for downloading at the following links: mobango.com, aptoide.com, getjar.com and itch.io.

The OpenWebGIS now as Android app
openwebgis

The OpenWebGIS is a new free&open Geographic Information System (GIS). In this GIS you can use the extensive mathematical functionality to calculate and analyze your data. Using OpenWebGIS you will get a Geographic Information System at your disposal, it may be similar in functionality to some desktop GIS. Please support this project. The OpenWebGIS for Android has online and local versions. In local version, you can use OpenWebGIS without having to connect to the server of OpenWebGIS and even without Internet connection. In local version, some functions do not work, but in future there will be the modification of these functions for the local version. Online full functionality web version of OpenWebGIS is at http://opengis.dlinkddns.com/gis/opengis_eng.html. The OpenWebGIS blog and full list of articles about OpenWebGIS provide a lot of information about possibilities for users' data operating. Online version is adapted for Mozilla Firefox and Google Chrome browsers. In other browsers, OpenWebGIS may not display and work correctly.

About OpenWebGIS and 3D maps at Cesiumjs.org
openwebgis

Please read information about OpenWebGIS and 3D maps at Cesiumjs.org here: http://cesiumjs.org/demos/OpenWebGIS.html.Cesium is a JavaScript library for creating 3D globes and 2D maps in a web browser without a plugin. It uses WebGL for hardware-accelerated graphics, and is cross-platform, cross-browser, and tuned for dynamic-data visualization. Cesium is used in OpenWebGIS primarily to create 3D View of the maps.

Extrude image to 2D, 2.5D and 3D layers on the map
openwebgis


In OpenWebGIS a new function has been created to manipulate images.
With the help of this function, you can calculate and get the height (height and altitude) of each pixel of your image. The calculation is performed based on the luminance (brightness) of the pixel. These estimates are used for the creation of:

  1. Vector layer (consisting of squares the number of which is equal or less than a number of pixels - it all depends on the settings you specify);

  2. Layer that consists of 2.5D columns based on "OSM Buildings" technology. For more information about "OSM Buildings" read here: "Integration of OpenWebGIS with OSM Buildings JavaScript library";

  3. The three-dimensional (3D) layer-based technology Cesium. For more information about "Cesium" read here:"3D maps, new version of Cesium JavaScript library and OpenWebGIS".

Spatial and temporal distribution of earthquakes in the USA and adjacent areas
openwebgis

The article is written to demonstrate the new capability of creating animated maps in OpenWebGIS using 2.5D columns. Before reading this article I recommend to read another one: Spatial and temporal distribution of earthquakes in Chile and adjacent areas (1960-2015).

French interface of OpenWebGIS - Test ver./L'interface française de OpenWebGIS - La version de test
openwebgis

OpenWebGIS with French interface is available here.

More than a month ago, I asked for help in translating OpenWebGIS interface into other languages. It was described for all users how and what to do in this article: "Help to create a free online OpenWebGIS interface in your own language". At the moment, few people have responded to this call for help to make free and open source software available to more people.
But since I can not wait and want to experiment as soon as possible with the interface in other languages, I translated the interface from English into French with the help of automatic translation (https://translate.google.com). Once again I draw your attention: the translation has been done automatically, so it certainly is full of errors and inaccuracies, but since this is an experiment, I ask not to judge strictly and help me with this translation.

Spatial and temporal distribution of earthquakes in Chile and adjacent areas
openwebgis

Initial data on earthquakes was selected from the database of "Earthquake Archive Search" with the help of menu item in OpenWebGIS: "GeoDataBase-> Earthquakes Database".
For the analysis we choose a rectangle with coordinates:
lower left longitude: -80.131640; lower left latitude: -56.006573; upper right longitude: -65.805468; upper right latitude: -16.608122.
Magnitude range: from 5 to 10.
Date & Time(UTC): from 1960-01-01T00:00 to 2015-09-21T09:48.

200 million years of the dinosaurs life in a few seconds on the map
openwebgis
Free online geographic information system (GIS) called OpenWebGIS provides an opportunity to sample data from the Paleobiology Database (Paleontological database). This was described in detail in the article "The information tools(data base and GIS) to help paleontologists in their scientific researches". You can make your selections and apply them automatically on the map using the menu item of OpenWebGIS "GeoDataBase-> Paleobiology database".
OpenWebGIS has various functions to analyze these and other data. For example, users can create animated maps based on attribute with the date/time values. This is described in detail in this article: "Embedding animated maps of OpenWebGIS in your sites". Until the last moment, all the articles on OpenWebGIS stated that: "Dates/times in the field with date must be in format ISO8601: yyyy-mm-ddThh:mm:ss (for example:'2015-09-17T18:00:00'). It is necessary for animation in OpenWebGIS. "
It is well understandable. But how to animate your data if you do not have detailed information about the months, days, minutes, and, for example, there is only a list of years (1996, 1997, 1998 ... 2015)? Let`s assume it can be solved by adding to the data field with the years the following string ('-01-01T00: 00: 00'). But thus how to animate processes that lasted millions of years?
