API Reference This reference reflects Leaflet 0.7. Docs for 0.6 are available in the source form (see instructions for running docs). Map The central class of the API — it is used to create a map on a page and manipulate it. Usage example Creation Options Map State Options Interaction Options Keyboard Navigation Options Panning Inertia Options Control options Animation options Events You can subscribe to the following events using these methods. Methods for Modifying Map State Methods for Getting Map State Methods for Layers and Controls Conversion Methods Other Methods Locate options Zoom/pan options Pan options Zoom options fitBounds options The same as zoom/pan options and additionally: Properties Map properties include interaction handlers that allow you to control interaction behavior in runtime, enabling or disabling certain features such as dragging or touch zoom (see IHandler methods). map.doubleClickZoom.disable(); You can also access default map controls like attribution control through map properties: '

Doc d'installation Gisgraphy Before install and launch Gisgraphy, you must setup java (you needs JVM >= 1.5), postgres, and postgis. it is not, properly speaking, the installation of Gisgraphy, and if you already havn't Postgres, Postgis and java installed, you must install it first. a tutorial is provided here for linux and here for windows Download a Gisgraphy distribution Fisrt you have to download a distribution here. Download a tar.gz file, if you are on Linux or download a zip file, if you are on windows. Then extract it : tar xvf YOURFILE if you're on linux or double click on the file if your on Windows

Import Geotagged Photographs into ArcMap By Mark Romero Esri Imagery Team You can easily import geotagged digital photographs into your map and integrate them directly into your existing geodatabase using the new GeoTagged Photos To Points tool available in ArcMap 10.1. The tool creates a point feature class in the geodatabase and, as an option, attaches the photos to the point feature class so they can be easily managed along with your other data. You will need at least an ArcGIS for Desktop Standard license and your output feature class must be in an ArcGIS 10 or higher geodatabase. Import photos from your smartphone into ArcMap using the new GeoTagged Photos To Points tool.

Web mapping client comparison v.6 This comparison aims to serve as a basis for those seeking a first approach to Web mapping technologies at the client side. In the sixth version a number of projects have been added and the whole set of clients has been categorized in order to distinguish them better, since there are currently forty four (44) Web mapping clients in the comparison. Web mapping clients play a significant role in Geoportals of Spatial Data Infrastructures (SDI) allowing the visualization of spatial data from several sources. Smallest-circle problem The smallest-circle problem in the plane is an example of a facility location problem (the 1-center problem) in which the location of a new facility must be chosen to provide service to a number of customers, minimizing the farthest distance that any customer must travel to reach the new facility.[3] Both the smallest circle problem in the plane, and the smallest bounding sphere problem in any higher-dimensional space of bounded dimension, may be solved in linear time. Characterization[edit] Most of the geometric approaches for the problem look for points that lie on the boundary of the minimum circle and are based on the following simple facts: The minimum covering circle is unique.The minimum covering circle of a set S can be determined by at most three points in S which lie on the boundary of the circle. If it is determined by only two points, then the line segment joining those two points must be a diameter of the minimum circle. Linear-time solutions[edit]

Doc d'installation Nominatim This page describes the general installation process for Nominatim. It is assumed that you are familiar with basic system and database administration. There are also more detailed step-by-step instructions for the following operating systems: Nominatim/Installation/CentOS Bentley Geospatial Management: Spatially Relating All Your Content in ProjectWise ProjectWise Geospatial Management extends the ProjectWise environment with a geospatial view and gives geospatial context to any information. Drawings, maps, models, images, vendor-specific GIS formats, and business documents in their originally intended form can all be related spatially in ProjectWise. This provides a practical and rapidly deployable system of organization, where the common denominator is spatial location.

Haversine formula The haversine formula is an equation important in navigation, giving great-circle distances between two points on a sphere from their longitudes and latitudes. It is a special case of a more general formula in spherical trigonometry, the law of haversines, relating the sides and angles of spherical triangles. The term haversine was coined in 1835 by Prof. James Inman. These names follow from the fact that they are customarily written in terms of the haversine function, given by haversin(θ) = sin2(θ/2). The formulas could equally be written in terms of any multiple of the haversine, such as the older versine function (twice the haversine).

ExifTool by Phil Harvey Read, Write and Edit Meta Information! Also available --> Utility to fix Nikon NEF images corrupted by Nikon software ExifTool is a platform-independent Perl library plus a command-line application for reading, writing and editing meta information in a wide variety of files. GeoTag: An OS X Application to tag photo locations GeoTag Version 3 GeoTag Version 3.3 Screenshot GeoTag is a free OS X application that allows you to update image metadata with geolocation tags by panning and zooming in a map window and then clicking on the location where a photo was taken. It is a good way to add location information to photos or fine tune existing location information. Image file updates are performed using Phil Harvey’s ExifTool.

Start with psql command-line tool of PostgreSQL Today I will explain how to start using PostgreSQL command-line tool. SQL Shell is a psql command-line tool(psql stands for PostgreSQL). We have two ways to work with PostgreSQL either we use command-line tool or pgAdmin III GUI tool. Here I explain about command-line tool. As you already go through with all PostgreSQL SQL Commands in my last article, you can check all the available commands using command-line tool. Photo mapping Available languages — For tracing aerial photos, see Aerial imagery. Photo mapping, a popular mapping technique, can be a great timesaver - it can be far quicker taking photos of street signs or points of interest than either to write it down or fiddle with the GPS waypointing. What's more, since digital cameras add the date and time to each photo (in the EXIF data), and the GPS tracklog can be used to convert the time into your exact position, it's easy to match up the photos to the exact position they were taken. Simple photo mapping Use your camera to help you remember stuff.

Create Table using PostgreSQL statements in pgAdmin Today we learn how to create table using PostgreSQL statements in pgAdmin. Before reading this article you may want to know how to create table using pgAdmin GUI. Create Table using pgAdmin GUI A table is a set of data elements that is organized using a model of vertical columns and horizontal rows, the cell being the unit where a row and column intersect. Rate Limits Usage of the API is subject to rate limits. The limits are based on a moving window that tracks the number of requests you send per hour. An application can make up to 5,000 userless requests per hour to venues/* endpoints.
