The map is a graph depicting the natural geography, administrative region, and social condition of the earth's surface by using lines, symbols, colors, and text notes in a certain proportion. With the advancement of science and technology, the concept of maps is constantly evolving. For example, maps are regarded as “images and symbolic models that reflect natural and social phenomena”. Maps are “carriers of spatial information” and “transmission channels for spatial information”. Wait.
Ancient maps are usually painted on parchment or slate. The traditional maps are mostly paper. With the development of technology, electronic maps and other carriers have emerged.
The map is based on a certain drawing rule, using the drawing method, through the mapping synthesis on a certain carrier, expressing the spatial distribution of the various things on the earth (or other celestial bodies), the connection and the state of development and change in time.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
