Creating a webmap5/7/2023 At version 1.3 of the Python API, the WebMap class has been enhanced with the ability to easily add, remove layers and a few other basic operations. In the mapping module, web maps are represented using a WebMap class. 6. If you are interested in learning more about this specification, refer to this documentation. A web map contains a JSON defining the bookmarks, layers, their symbology, order and other cartographic information. Working with web mapsĢD maps in your GIS are stored as web map items. In this guide we will observe how to work maps and scenes using the arcgis.mapping module. Web maps and scenes are stored as items on your portal and their content is in JavaScript Object Notation (JSON), a text format that can easily be transferred, stored, and edited. To get and overview, visit the product documentation for web maps and web scenes. Web maps can also be configured for offline use if your mobile workers work in areas without a reliable internet connection. When used with an internet connection, web maps allow mobile workers to access the same data used in the office. A web scene is analogous to a web map but in the 3D space. Web mapIf your mobile workers always have an internet connection, even out in the field, provide a web map. To sign off, here is an article that focuses on other FME tips that could be useful for when you rasterize data or are online mapping.An ArcGIS web map is an interactive display of geographic information through a composition of web layers, basemap and much more. If you have any questions, don’t be afraid to comment below. I hope this article makes Online Mapping, Web Mapping or Web GIS a little clearer to you. Click here for a step-by-step guide on how to distribute data using FME. The request is then sent to FME Server which processes it and returns the data to the user. Once the polygon is drawn, the user can continue building up a request by selecting the layers they wish to download and the format and the coordinate system of the returned data. This application provides an interface for users to select a study area by drawing a polygon. The above application demonstrates FME Servers Data Download service and how it can integrate web maps such as Google Maps and ArcGIS Server. This example demonstrates the FME Server Data Download service can integrate with web maps such as Google Maps and ArcGIS Server. You can make a web map with any projection. You can even distribute data with web maps using FME so your organization can function more efficiently and make more use of your data! You can use the hosted tile layer in web maps. This will cause two items to be created: a copy of your vector tile package and a hosted tile layer. Confirm that the option for Add vector tile package and create a hosted tile layer is selected. There are several ways to distribute your data. Browse to your desktop, choose Bogot.vtpk, and click Open. Data distribution can also alleviate other issues related to servers and slow network access. Data distribution can improve data availability. The distribution of (use) data is simply taking data and sharing it with others. For a more detailed guide on how to rasterize data using FME, here is an article for you! FME Server can be used to increase performance if the workspace is divided into multiple jobs. It can also be used with Google Earth and other web mapping platforms.įME Server allows you to automate the creation of web map tiles too. The results of the tiling process are not limited to a single mapping platform. Only FME Desktop is needed to start making them. It is really easy to start making raster tiles with FME. Once vector data has been transformed to raster data FME can be used to create web map tiles using the WebMapTiler. You can use FME and its transformers to rasterize the vector data. To rasterize data, you need to source vector data. This raster data that can be displayed on any device. Rasterization is the process of converting vector data into a raster tile. The edges of the vector polygons become entire cells when converted to raster. The difference between vector and raster data.
