| - | ===== TerraView 5.0 - Main concepts related ===== | + | ===== TerraView 5.0 - Main concepts ===== |
| - | The new concepts adopted in TerraLib/TerraView are summarized here in a way users of TerraView 4.x.x will quickly understand the main changes. | + | The new concepts adopted in TerraLib/TerraView 5.0 are summarized here in a way users of TerraView 4.2.2 will quickly understand the main changes. |
| - | |Features |DataSource|From: TerraView 4.3.2| To: terraView 5.0|Stored (access or Postgis)| | + | |
| - | |Converter|database.mdb|Vector Layer| Vector|It will be stored into the datasource defined by the user| | + | |
| - | | | | Tabular Layer|Tabular|It will be stored into the datasource defined by the user| | + | |
| - | | | | Raster Layer|Raster|It will be saved in Directory defined by the user| | + | |
| - | | | |External Tables|Tabular|It will be stored as a tabular| | + | |
| - | | | |View|Map Display|the View can be compared to the Map Display (the view projection is the Map Display SRID)| | + | |
| - | | | |Theme|Layer|Layer showed in a Map Display (reprojected to the Map Display SRID)| | + | |
| - | | | |Theme Visual|Style|The Visual concept is the Styler store inside the Project file| | + | |
| - | | | |External Tables|Tabular|It will be stored as a tabular| | + | |
| - | | | ||Project File |For each Layer, the project file keep one reference to one dataset located in a datasource and other information like style (visual),etc.| | + | |
| - | | | ||DataSource|Datasource is a location where to find data (Postgis database, access database,dir of vectos, dir or rasters , url)| | + | |
| - | | | ||Connector|It is a set of parameters used to identify an existing datasource to the application (each datasource can have a specific set of parameters). Also used to create a new datasource to insert data on it.| | + | |
| + | |**From: TerraView 4.2.2**| **To: terraView 5.0**| **Rationale**| | ||
| + | | |DataSource |Data Source is a location where to find data (Postgis Database, Microsoft Access Database, Directory of vector files, Directory of raster files and URL)| | ||
| + | | |Connector|It is used to registry an existing datasource (or to define a new datasource) into a file called ''datasource.xml'' | | ||
| + | | |Project File (*.tview) |For each Layer, the ''Project'' file keep a reference to a dataset stored in a datasource and also keep its style(point/line/polygon) of visualization,etc.| | ||
| + | | |Layer Explorer |It lists all Layers referenced in a Project| | ||
| + | |Projection|SRID| It is a code given by EPSG to each known projection | | ||
| + | |Infolayer, Vector| Vector Dataset |It will be a dataset stored into the datasource defined by the user| | ||
| + | |Infolayer, Raster|Raster Dataset |It will be a raster file stored in a Directory defined by the user (outside the database)| | ||
| + | | Tabular Layer|Tabular|It will be a dataset stored into the datasource defined by the user| | ||
| + | |External Tables|Tabular|It will be dataset stored as a tabular layer into the datasource defined by the user| | ||
| + | |View|Map Display|A ''View'' can be compared to the ''Map Display'' (the view projection is the Map Display SRID adopted to visualize all layers)| | ||
| + | |Theme|Layer|Layer showed in a Map Display (reprojected to the Map Display SRID)| | ||
| + | |Theme Visual|Layer Style|The Visual concept is the Layer Style stored inside the Project file| | ||
