Kartograph KML Reference - KML - Google Code This section contains an alphabetical reference for all KML elements defined in KML Version 2.2, as well as elements in the Google extension namespace. The class tree for KML elements is shown below. In this diagram, elements to the right on a particular branch in the tree are extensions of the elements to their left. For example, Placemark is a special kind of Feature. It contains all of the elements that belong to Feature, and it adds some elements that are specific to the Placemark element. KML is an open standard officially named the OpenGIS® KML Encoding Standard (OGC KML). The complete XML schema for KML is located at Note: Click an element name in this diagram to jump to its entry in the reference section. Note that abstract elements (shown in boxes in the diagram) are not actually used in KML files. All elements derived from Object can have an id assigned to them.

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. There exists a wide variety of free and open source software (FOSS) projects that make the creation and configuration of Web mapping clients easier. This study presents a wide collection of Web mapping clients capable to access Open Geospatial Consortium (OGC) Web services, and examines some of their most relevant properties, but does not represent an exhaustive analysis of their technical features. Below is a graph showing the relation between free and open source Web mapping clients.

MapTiler и GpsVP Как подготовить готовую растровую карту (или снимок) и работать с ней на наладонном компьютере (КПК). Обсудить в форуме Комментариев — 1 Оглавление 1. Введение Для полевой работы с GPS-устройствами часто бывает необходимо загрузить туда привязанные растры (например, космические снимки, планы лесонасаждений, топокарты) и векторные данные. Используемые программы: MapTiler - для подготовки растровых данных для КПК и в Garmin. 2. Смысл работы заключается в создании геопривязанной мозаики растров с несколькими уровнями детализации. Скачиваем MapTilerи устанавливаем его на настольный ПК. На следующем этапе нужно указать нужный нам растр (поддерживаются TIFF/GeoTIFF, MrSID, ECW, JPEG2000, Erdas HFA, NOAA BSB, JPEG). На следующем этапе нужно определить систему координат и проекцию. Если нас такое определение не устраивает, можно задать проекцию вручную и обязательно нажать Set: Определяем каталог, куда положим готовые растры. 3. Подгрузка растровой карты, созданной с помощью MapTiler

Projections on Bing, Google I have lately seen several blogposts confused about which datum and projection Microsoft’s Live Maps (Virtual Earth) and Google Maps use. As most people already know by now, they render the round earth onto a flat screen using a Mercator projection. I think the confusion comes from that they actually use two spatial reference systems at the same time: Geographic Longitude/Latitude coordinatesystem based on the standard WGS84 datum. So when is what used? The Javascript API’s use (1) as input when you want to add points, lines and polygons. If you want to create image overlays, or roll your own tile server on top of the map, you will need to project your images into a spheric mercator projection. Here’s a bit of facts about the two projections: The valid range of (1) is: [-180,-85.05112877980659] to [180, 85.05112877980659]. The valid range of (2) is: [-20037508.3427892, -20037508.3427892] to [20037508.3427892, 20037508.3427892] So why this weird extent for the latitude?

Geography - How Do You Define A Country? When people ask how many countries there are in the world,they expect a simple answer. After all, we've explored the whole planet, we have international travel, satellite navigation and plenty of global organizations like the United Nations, so we should really know how many countries there are! However, the answer to the question varies according to whom you ask. Most people say there are 192 countries, but others point out that there could be more like 260 of them. So why isn't there a straight forward answer? The problem arises because there isn't a universally agreed definition of 'country' and because, for political reasons, some countries find it convenient to recognize or not recognize other countries. For example, Taiwan claims to be a country, but China states that Taiwan is just another part of China. So, how do governments define what makes a country? There are three terms you come across when you try to discover how countries are defined. The Montevideo Convention 1. 2. 3.
