GeoPQL
The Geographical Pictorial Query Language (GeoPQL) is a system implemented according to the ESRI standards and assumes the form of the first stand alone extension for the suite of ESRI ArcGis 9.x applications.
It is a system implemented according to the ESRI standars, from which it inherits the data format and many functionalities, and has a user friendly graphical user interface of simple and immediate utilization.
GeoPQL is, in fact, a system able to formulate visual queries of increasing complexity, utilizing a minimum time and with the certainty of always true results, characterized by a very high precision (these last two things are, obviously, function of the data quality stored in the geographical database used).
It has been completely implemented utilizing the ArcObject technology and units the computation power with the use simplicity.
In this system all the base functions of browsing and drawing which are present in ArcGis are implemented, as well as ad hoc functions, such as a very power and transparent geo-processing (an extension of that one already present in ArcGis), the visual analysis in real time of the drawing which allows to express the pictorial query, as well as an SQL-like language which describes the drawn query, etc.
