ARCGIS PRO

ArcGIS Pro is the premier professional desktop #GIS application from Esri. With ArcGIS Pro, you can visualize, edit, and analyze your geographic data in both 2D and 3D. After you create projects, maps, layers, tools, and more, ArcGIS Pro has several options for sharing your work with others.

ORTHO MAPPING

• ArcGIS Pro now supports the production of georeferenced ortho products from images from drones, satellites, and digital and scanned aerial photography. These products include georeferenced orthomosaic datasets, georeferenced orthomosaics stored as TIFF or CRF, digital elevation models (DEM), and digital surface models (DSM).
• You can share a georeferenced orthomosaic dataset as a dynamic image service or cached image service. You can also use the orthomosaic dataset to generate image tiles with the Split Raster tool, or create orthoimage scenes with the Export Mosaic Dataset Items tool.

GEOREFERENCE IMAGERY AND CAD DATA

• You can now georeference your imagery and CAD data in ArcGIS Pro.
• Georeferencing imagery defines the locations on the image using map coordinates and assigns the coordinate system of the map frame to the image. Georeferenced images can be viewed, queried, and analyzed with your other geographic data. You can use the georeferencing tools on the Georeference tab to georeference an image.
• Georeferencing CAD data is the process of spatially adjusting a CAD drawing. After using the georeferencing tools, you can rotate, move, and scale your CAD data, or create control points to perform a transformation.

PORTAL ANALYSIS

• You can now use ArcGIS Pro to access a number of analysis tools in the ArcGIS platform, including Feature Analysis tools, Raster Analysis tools, and GeoAnalytics tools. When you use these tools, they run on your portal’s federated server instead of on your local desktop machine, and they create new output layers in your portal instead of in a local folder or geodatabase.
• You can access the tools that are available in your active portal in the Portal group on the Analysis tab on the ribbon, or from the Portal tab in the Geoprocessing pane. To use these tools, you must be connected to Portal for ArcGIS.

GRATICULES

Graticules, which can be used on layouts to show location in geographic coordinates, can now be imported into ArcGIS Pro from your existing ArcMap map documents (.mxd) or inserted from a style. You can customize graticules by rearranging gridlines and ticks and modifying the appearance of labels.

MULTIPATCH EDITING

• Editing in ArcGIS Pro now includes support for multipatches. In the Create Features pane, you can create multipatch features using the Create 3D Geometry tool Create 3D Geometry, or use the Multipatch tool 3D Models to create multipatch features from 3D models.
• In the Modify Features pane, you can now use the Vertices tool Edit Vertices to extrude a multipatch feature in a scene. You can drag an existing face; add a new face and drag it outward or inward to create a hole; or create a ridgeline across a face and drag it to create two angular faces, such as those comprising a pitched rooftop. You can also copy a 2D polygon feature to a multipatch layer using Paste Special Paste and extrude it as a multipatch feature.

ARCADE SCRIPTING FOR LABELING AND RENDERING

ArcGIS Pro now supports the Arcade expression language. Arcade expressions are portable throughout the ArcGIS platform. Arcade expressions work in Runtime, ArcGIS Pro, ArcGIS Online, and JavaScript API, while other languages do not. Areas where Arcade expressions are used include labeling, symbology, and range aliases.

Esri

A geodatabase is an alternate way to store #GIS information in one large file, which can contain multiple point, polygon, and/or polyline layers. ESRI is pushing the geodatabase idea, because it is a less “messy” way of organizing data than having multiple shapefiles. in multiple folders. Geodatabases allow users to thematically organize their data and store spatial databases, tables, and raster datasets.

There are two types of single user geodatabases: Personal Geodatabase and File Geodatabase.

Personal geodatabases—All datasets are stored within a Microsoft Access data file, which is limited in size to 2 GB.

A personal geodatabase is a Microsoft Access database that can store, query, and manage both spatial and nonspatial data. Because they are stored in Access databases, personal geodatabases have a maximum size of 2 GB. Additionally, only one person at a time can edit data in a personal geodatabase. Personal geodatabases can also contain domains, use subtypes, and participate in checkout/check-in replication and one-way replicas. You create personal geodatabases in #ArcGIS.

File geodatabases—Stored as folders in a file system. Each dataset is held as a file that can scale up to 1 TB in size. The file geodatabase is recommended over personal geodatabases.

A file geodatabase is a collection of files in a folder on disk that can store, query, and manage both spatial and nonspatial data. A file geodatabase can be used simultaneously by several users, but only one user at a time can edit the same data. Therefore, you can have multiple editors accessing a file geodatabase, but they must be editing different data. The default maximum size of datasets in file geodatabases is 1 TB. The maximum size can be increased to 256 TB for large datasets (usually raster). This is controlled by a configuration keyword. File geodatabases can also contain subtypes and domains and participate in checkout/check-in replication and one-way replicas. You create file geodatabases in ArcGIS.

File geodatabases is preferred storage for Esri ArcGIS and have many benefits including:

1 TB of storage limits of each dataset

Better performance capabilities than Personal Geodatabase

Many users can view data inside the File Geodatabase while the geodatabase is being edited by another user

The geodatabase can be compressed which helps reduce the geodatabases’ size on the disk

Data storage decision is very important … choice and pick wisely … Stay tuned with Seerab : )
