Advanced Import provides a way to import multiple images that can comprise of different formats and different coordinate systems.
Created by Esri, ArcGIS Online is an online, collaborative web GIS that allows you to use, create, and share maps, scenes, apps, layers, analytics, and data. Geographic Imager can import Map Feature Layers, Map Image Layers, Map Tile Images, web services. See ArcGIS Online and ArcGIS Service for more information.
ArcGIS web service
An ArcGIS Server web service represents a GIS resource—such as a map, locator, or image—that is located on an ArcGIS Server site and is made available to client applications.
Avenza Maps is a mobile map application that allows users to download maps for offline use on an iOS, Android, and Windows smartphone or tablet.
Avenza Map Store
The Avenza Map Store is an in-app map store that contains more than 500,000 maps for sale.
Geographic Imager Channel Management allows you to control channel mapping and assignment of channel color roles for false-composite multiband imagery.
When georeferencing, a control point has both pixel (x,y) coordinate and world coordinate specified is considered a control pair.
In georeferencing, a point on the map with known pixel (x,y) coordinates.
Coordinate systems enable geographic datasets to use common locations for integration. A coordinate system is a reference system used to represent the locations of geographic features, imagery, and observations such as GPS locations within a common geographic framework.
custom coordinate system
A user-defined coordinate system with custom parameters.
Individual entries in the geodetic datasource are known as data source objects. Different types of data objects are available for different types of definition. Objects contained in the geodetic data source are: Angular Units, Coordinate Systems, Datum Transformations, Ellipsoids, Envelopes, Horizontal Datums, Linear Units, and Prime Meridians.
destination coordinate system
The coordinate system of the destination image. For example, the coordinate system of an image after transformation.
A Digital Elevation Model (DEM) is a representation of ground surface topography or terrain and is generally represented as a raster or as a triangular irregular network (TIN). DEMs are often used for shaded relief maps.
In MAPublisher, the Expression Builder is used to create and edit expressions. Expressions are built using a combination of names, operators and functions. It is used in a number of locations such as when creating new attribute values and properties, making selections or apply styles.
A Geographic Imager tool that crops spatial images based on crop areas defined by pixel coordinates, by geographic coordinates, by using a coordinate system envelope, by proximity, or by extents of a vector file.
An extensive geodetic parameter database included in Geographic Imager. It contains all the latest updates from the widely used EPSG Geodetic Parameter Dataset maintained by the Geodesy Subcommittee of OGP (International Association of Oil and Gas producers) as well as custom systems maintained by Avenza.
geographic coordinate system
Geographic coordinate system locations are defined in terms of the position on a globe using latitude and longitude values. The angles of latitude and longitude are based on a point at the centre of the earth. As the earth is not a perfect sphere a number of globes (spheres, spheroids) exist in mapping each with slightly different centre points and characteristics. As locations are defined by degrees, distances cannot be accurately measured. The most common geographic coordinate system is the World Geodetic System 84 (WGS84).
A Geographic Imager tool used to reference or rectify images. The tool allows you to reference or rectify images.
A folder that contains files compatible with the Avenza Maps app. A map package can be uploaded by a vendor to be put for sale on the Avenza Map Store.
A Geographic Imager tool that creates a single composite georeferenced image from multiple input georeferenced images.
projected coordinate system
Projected coordinate system locations are defined using Cartesian x, y coordinates on a flat, two-dimensional surface. This enables accurate measurements of distance, angles and areas. Projected coordinate systems are based on a sphere (for example WGS84) that is projected onto a flat plane. Projected coordinate systems are often referred to as projections. Common projected coordinate systems include Universal Transverse Mercator (UTM) and Lambert Conformal Conic.
In the Georeference tool, the process of applying a transformation method to an image, often to remove distortion. Image rectification may involve rotating, scaling, and skewing the image.
In the Georeference tool, the process of aligning geographic data to a known coordinate system.
A file that contains the relationship between source image coordinates (pixel locations) and real-world reference coordinates (lat/long or other real-world coordinate units). Common reference files include World files, Blue Marble Reference files, MapInfo Tab files, and ER Mapper Reference files. Some reference file formats can hold additional information such as coordinate system information.
A series of commands that tells Adobe Photoshop to perform a set of specified actions, such as applying different filters to selections in an open document. Scripts automate repetitive tasks and are often used as a creative tool to streamline tasks that might be too time consuming to do manually.
Shaded relief, or hill-shading, simulates the cast shadow thrown upon a raised relief map.
source coordinate system
The coordinate system of the original image. For example, the coordinate system of an image before transformation.
A type of database that is optimized for storing and querying data that represents objects defined in a geometric space such as points, lines, polygons, tables, text and can include other more complex objects such as coverages and networks.
A Geographic Imager tool that is used to create the look of shaded relief.
A Geographic Imager tool used to specify a destination coordinate system for image transformation (projection).
A Geographic Imager tool that creates multiple images from a single image.
A model representing the world in points, lines, and areas. For example, points can represent locations, lines can represent streets, and areas can represent countries.
A vertex (plural: vertices or vertexes) is a point where two or more curves, lines, or edges meet.
Image tiles that can be used for online map purposes. Google Maps, Bing Maps, OpenStreetMap, Tile Map Service, and MapBox formats are supported.
Web Map Service (WMS) is a web server that can be accessed to acquire raster content in a variety of formats.
