How can I describe this data using a graph?
Earth scienceA graph is a graphical representation of data. Visualizing data through graphs helps to detect patterns, trends, relationships, and structures in data. Use graphs in conjunction with maps to explore data or help tell a story. Graphs can be created from both tabular and raster data, and there is a different set of graphs for

Create additional ‘fields’ in GDB domain system table (GDB_items)?
Geographic Information SystemsWhat is a GDB table? The internal structure of the geodatabase is represented as a series of simple tables called the geodatabase system tables (the tables prefixed with GDB_), which track the contents of each geodatabase. They essentially describe the geodatabase schema that specifies all dataset definitions, rules, and relationships. Which geodatabase repository table stores
Exporting layer to PostgreSQL / Inserts per Transaction
Geographic Information SystemsHow many inserts per second can Postgres handle? If you’re simply filtering the data and data fits in memory, Postgres is capable of parsing roughly 5-10 million rows per second (assuming some reasonable row size of say 100 bytes). If you’re aggregating then you’re at about 1-2 million rows per second. How to store large
Advantages either way between GML and Shapefiles?
Geographic Information SystemsWhat are the main advantages of using shapefiles? A primary advantage of shapefiles is that this simple file structure draws faster than a coverage does. This may be why the shapefile data structure was developed for ArcView GIS, a software program that was originally designed for data viewing rather than analysis. What is the difference

Difference between Merge Raster Layers and Build Virtual Raster in QGis?
Geographic Information SystemsWhat is a virtual raster QGIS? A virtual raster (VRT) is a special type of file that references one or more existing raster datasets and combines them into a single virtual layer. Can you merge raster layers in QGIS? QGIS uses the the GDAL merge tool, which is a very fast and efficient tool, to
Creating DEM after converting MapInfo tab files to ArcGIS Desktop?
Geographic Information SystemsHow do I convert MapInfo to ArcGIS? ArcGIS will not read MapInfo files directly; instead, the user must create a MapInfo Interchange Format (MIF) file in MapInfo (using Table > Export) which can then be imported into ArcGIS. MIF is a file format which enables both graphical and tabular data from MapInfo to be imported
