In diesem Artikel möchte ich zeigen

In diesem Artikel möchte ich zeigen, wie man Geometrieobjekte aus einer ESRI ArcSDE-Datenbank mit einem OpenSource GIS Client visualisieren lassen kann. Dieser Ansatz ist nicht komplett quelloffen, da sich die verwendete Feature Data Object (FDO) API auch der proprietären ArcSDE API bedienen. Als GIS-Viewer wird die Bibliothek DotSpatial eingesetzt. In einer vor kurzem veröffentlichten Artikelserie habe ich beschrieben, wie man die FDO API mit DotSpatial in C# als Datenprovider verwenden kann. Als beispielhafte Datenquelle diente ein ESRI Shapefile.
Bei einer ArcSDE als Datenquelle wirds nur leicht anders. Das ist das Schöne an der FDO API: wenn man das Konzept und die Vorgehensweise einmal begriffen hat, ist die Verwendung der FDO API unabhängig vom Datenprovider. Nur einige wenige Dinge ändern sich.

In this article, I will show how you visualize geometry objects from an ESRI ArcSDE database with an OpenSource GIS client can. This approach is not completely open source, because themselves used feature data object (FDO) API of also the proprietary ArcSDE API. The library DotSpatial is used as GIS-Viewer. In a series of articles published recently, I described how you can use the FDO data provider API with DotSpatial in C#. An ESRI shapefile. served as a sample data source
in an ArcSDE as a data source is only slightly different. That's the beauty of the FDO API: If even has grasped the concept and modus operandi, API use the FDO is independent of the data provider. Only a few a few things change.

In this article I want to show how one can be used to visualize geometry objects from an ESRI ArcSDE database using an Open Source GIS client. This approach is not entirely open source, as the Feature Data Object (FDO) API and the proprietary API used ArcSDE use. As a GIS viewer library DotSpatial used. In a recent article series, I described how the FDO API with DotSpatial in C # can be used as the data provider. As exemplary data source ESRI shapefile. Served
In an ArcSDE data source it gets only slightly different. That's the beauty of the FDO API: if you have grasped the concept and the procedure once, the use of the FDO API is independent of the data provider. Only a few things are changing.

In this article I would like to show, how one can let geometry objects from a ESRI ArcSDE database with an open SOURCE GIS client visualize. This approach is not complete, there the used feature DATA Object (FDO) API also the proprietary ArcSDE API avails itself. As GIS Viewer the library DotSpatial is used.In a recently published series of articles I described, how one can use the FDO API with DotSpatial in C# as data providers. As exemplary data source a ESRI Shapefile.
Bei of a ArcSDE served as data source becomes it only slightly differently. That is the beautiful to the FDO API: if one understood the concept and the approach,the use of the FDO API is independent of the data provider. Only some few things change.
