Polygons for the state of Michigan are combined to extract one raster for the state.

Raster Extract — Combine Polygons by Attribute 31 March 2017

The Raster Extract process now has a 'Combine by Attribute' toggle for the 'By Polygons' mode. This gives you the ability to treat multiple polygons with identical attributes as one region resulting in one output raster for each unique attribute. With the toggle off, separate rasters are created for each polygon.

All elements with blank or no attribute assigned will be combined as a single region. Attributes are matched by string value not by record, so different records sharing the same attribute value will be combined to form one region.

Radiometric Correction of Satellite Images 21 January 2016

The Radiometric Correction process in TNTmips (Image / Radiometric Correction) calibrates images acquired by satellite optical sensors to radiance or reflectance values. These corrections allow more accurate assessment of ground surface properties and facilitate comparison between images acquired at different times or for different areas.

Automatic Image Georeferencing 6 January 2016

The Auto-Register operation in the Georeference process (TNTmips and TNTedit) can now automatically georeference geolocated aerial images with unknown orientations using a reference image. Geolocated images have map coordinates for only a single point (such as a GPS camera position recorded in EXIF metadata, nominally the image center). The Automatic method in Auto-Register uses keypoint matching to establish the image orientation relative to the reference (if necessary), then uses image cross-correlation to find additional control points. A new separate process to perform auto-registration on large sets of aerial images is also now available (Image / Auto-Register to Reference Image).

Spatial Display: Vector and Shape Layer Controls 16 December 2015

Layer controls dialogs provide access to display settings for specific types of layers. Open the Vector Layer Controls window by left-clicking on the vector layer's icon button in the Display Manager or by right-clicking on the layer name and choosing Controls from the popup menu. Shape Layer Controls are opened the same way for shape layers.

The layer controls are organized in a set of tabbed panels. The Object panel provides settings that pertain to the entire layer. A tabbed panel for each of the vector element types: Points, Lines, Polygons, Nodes, and Labels in Vector Layer Controls lets you set element specific controls to show and style elements, set datatips and dynamic labels, and label legend samples. The Shape Layer Controls dialog has an Elements tabbed panel with similar controls.

Spatial Display: Render to PDF 9 December 2015

The Render to PDF operation in TNTmips and TNTedit allows you to render the contents of the View window to a PDF file. The operation can render layers in simple groups or complex map layouts, including raster and geometric layers, WMS and ArcIMS layers, map grids, legends and scale bars, and text. Complex line and point symbols, including those created by CartoScripts, can be reproduced faithfully in the PDF file. Georeference information is automatically transferred, producing a Geospatial PDF file that can be used with the analysis tools in Adobe Reader to get coordinate readouts and make measurements. You also have the option to include layer controls in the PDF file so that any individual layer can be turned on or off in Adobe Reader. To use the Render to PDF operation, choose Display / Render to / PDF from the Display Manager.

UPDATED DataTip Technical Guides 3 December 2015

DataTips are provided in TNTgis to show selected attribute information for spatial layers under or near the screen cursor when it is paused in the View window. DataTips can show the cell value from a raster layer, database attributes for elements in geometric objects (vector, CAD, shape, Lidar, and TIN) and database pinmaps, and image thumbnails from a geotagged image database table. When you are displaying geometric data layers, you can choose to have the associated elements automatically highlighted in color when the DataTip is shown.
