Hi, this post is about four solutions about how to perform offline basemap creation for mobile mapping in Android or Apple IOS devices. For this first part. I will demonstrate about GeoPDF format that is widely supported in most GIS Software. I will demonstrate how to write GeoPDF in ArcGIS Desktop (ArcGIS Pro also has this functionality) and QGIS, followed by how to load the GeoPDF Map in a supported Android/IOS App. Unfortunately, when this video is made, the only app that can read GeoPDF is only Avenza PDF Maps (available in Android and IOS). The rest is no longer updated (TerraGO GeoPDF) or part of paid services (Global Mapper Mobile Pro). Utilizing GeoPDF for field mapping basemap is very effective and simple. All data in one file. They are structured and tailored according to your setting on the GIS Desktop. They also provide good loading performance as long as the file is not relatively huge. For the second part. I will demonstrate the ArcGIS Mobile Map Package (MMPK) forma...

This video tutorial below may be wont interesting for some people, but I made this tutorial with a single goal, helping people that still learning GIS and have a requirement to use GIS data to be analyzed in Google Maps or Google Earth. KML/KMZ is a native format for Google Mapping Products. It can store vector as vector or vector as raster or raster as raster. It is very convenient, although it usage in context of pure geospatial data format is limited.  There are some strategic aspect about KML/KMZ usage. The most important things is you can host your geospatial data for free in Google MyMaps. You can made simple webmap that has basic webgis functionalities, powered by complete and strong basemap and online imagery basemap, and you can do multiuser editing. KML/KMZ data supporting multiuser although it is a file based data. So if you are interested to use this format, and your data is still on shapefile or geodatabase format, ArcGIS has the tool to convert it to KML/KMZ, and vide...
