Neither AutoCAD DXF nor AutoCAD DWG format provide coordinate system information. This example shows a typical case where documentation provided on the web site from which we have downloaded a DWG allows us to quickly and simply georeference the imported drawing. |

Neither AutoCAD DXF nor AutoCAD DWG format provide coordinate system information. This example shows a typical case where we import a DXF using an unknown coordinate system, but based on a lucky guess we accurately georeference the imported drawing. |

Example: Import an ESRI ADF File and Apply Style and Hillshading |
In this example we import an ESRI ADF format file that provides a raster terrain elevation data set for the region near Yosemite National Park in the United States. The data set imports as an image. We then use Style to style the image and to provide hillshading. |
A very technical example in which we import a BIL file that produces three images, each using one band from the BIL. We then create an image that uses the three bands for R, G and B. |
|
Import a CSV file by creating a New Data Source, copying and pasting the table conveyed by the CSV, prepping the table for use as a geocoded table and then creating a drawing. |

A companion topic to the Example: Import GIRAS vector LULC File and Style topic. We import a CTG LULC Grid Cell file containing raster data showing land use and land cover and then we use Style to provide a more understandable display. |
|
We import a raster data terrain elevation surface from USGS SDTS format using DDF files. |
|
We import a vector data roads drawing from USGS SDTS format using DDF files. We use the Select pane to quickly reduce the data to line objects only, excluding points and area objects. |

An intricate example showing how to use Manifold tools to adapt legacy data imported from E00 format into useful, modern form. |

Step by step examples showing how to link an image from an ECW file into a project and also how to import an image from an ECW file into a project. |

Import vector footprints for all buildings in the District of Columbia, using a GeoJSON file published as open data by Microsoft. |
|
A companion topic to the Example: Import CTG Grid Cell File and Style topic. We import a USGS land use file in GIRAS vector format and then we use Style to provide a more understandable display. |
|
Import an Ordnance Survey, UK, vector map in GML format from the OS Open Map - Local series. |
|
This topic provides a complete example that shows a simple, but typical, task involving spatial data. We import a country-sized data set from GeoPackage (GPKG) format, change all areas in the data to the boundary lines for those areas, and then save those boundary lines as a new drawing and table. |
|
KML files can contain GroundOverlay references to images that are stored in other files and which are intended to be used as part of the KML. Manifold will automatically import GroundOverlay images that are stored on the local machine or which are accessible through local network references as part of the KML import. |
|
MapInfo TAB format can store images as well as vector drawings. This example shows how multiple images at the same time can be imported from TAB format. |
|
Use the Scan Raw Binary File tool to scan and to prepare a configuration file, which we use to link an NLCD raw binary file providing land cover data for Delaware as a raster image. We use a standard palette to color the land cover data and then we assign a projection to the newly imported image so it can be used as a correctly georegistered layer in maps. |

Example: Import ERDAS GIS with GDAL and Assign Coordinate System |
A multistep example that covers import of an unwieldy format using GDAL, followed by use of Assign Initial Coordinate System and Repair Initial Coordinate System to deal quickly with real-life complications. |
Example: Create Terrain Elevation Raster from a NASA PDS Table |
A long, multistep example showing many powerful features of Manifold in various steps. We import terrain elevation raster data from a NASA PDS archive and style the images with an elevation palette and hillshading. We notice one of the images was wrongly georegistered by NASA, so we import the original LiDAR point data from a table in the PDS archive. We transform the imported table from 0 to 360 degree longitudes into +/-180 longitudes, construct a geometry field, and then we create a drawing from the table that shows the LiDAR point data in the table. Next, we use Kriging to create a terrain elevation raster from the LiDAR point drawing, and then we style that and hillshade it so it can be exactly overlaid on a Bing satellite layer to enhance the satellite photography with enhanced terrain relief. |
SQL Example: Extract Airport Runways from an OpenStreetMap PBF |
We write a simple SQL query using INNER JOIN to extract runway lines from an OpenStreetMap PBF of Cyprus, and to save those lines to a new drawing and table. |
Visit an ESRI web site, copy a URL, and then use that URL to connect to an ArcGIS REST web server that shows petroleum fields in Kansas, getting the data as a vector drawing layer. Style the layer as if it were local. ESRI refers to ArcGIS REST servers that provide vector data as feature servers. |
