G! Tools, facilitating the use of Bentley Map

A few days ago I started a development on . NET Visual Basic of Microstation, with which I hope to solve the limitation that Bentley Map has, with its Geospatial Administrator. To do this, I have captured an old pupil with whom we started Geofumar xfm There when coming out of the comal, with a good cappuccino and amareto we have found the changes that since V8i have been implemented in the "Bentley Map Fundamentals" y "Bentley Map Administrator".


That is simple, Bentley wants to be a CAD that makes GIS, and although it has a good acceptance in cadastral projects, the barrier that common users have when they first encounter Bentley Map must be broken. An ESRI, Manifold or AutoCAD Map user, who wants to do a project on his own, buys the package from the regional distributor after a while reading the manual realizes that he does not know where to start.

So for these, it arrives G! Tools for Bentley Map, a solution that I hope to have ready in a couple of months and that will run on PowerMap, with which it should be possible to start a project in Bentley Map, without using the Geospatial Administrator. One of the attractions is that it would bring a project template categories, layers and properties already created, and an example of a municipality for the user to decide what to take, discard or create new. For now I show you a preview:

What is the intention

The idea is in its initial part, a wizard that allows from a template project, from the map side, to structure what it requires without entering the Geospatial Administrator. Something like doing from ArcMap what is done in ArcCatalog, so that what is built as layers constitutes an xml structure ready to operate and connect to external data.

For this I defined five tabs that in this example I mean:

General information:  Here you select the project name, seed file and external data connections. With this, an xml schema is created, and a user workspace, for example:  Assistant assessor, Which will use only a series of layers and not all that the head of the department would see.

Gtools bentley map Categories: In this panel, you can select, from a list of pre-established categories, those of interest. For example, Catastral, Hydrography, Roads and Administration. Being able to also create new ones.

Lessons (Features): From the chosen categories, you can select those classes that are going to interest, for example:

Of the cadastral category, only the layer of apples and buildings, of the category hydrography only the axes of rivers and streams, of the road layer the axes of streets and of the Administrative layer the neighborhoods, sites and urban perimeter.

Class Properties: Here, taking into account the selected classes, the specific properties of each class can be defined or modified, for example:

The constructions class: orange line, yellow fill, transparency 50%, with attribute and cadastral key annotation, this same as primary key, path of photographs and connected via ODBC to the avaluocat table of a MySQL database and with display columns use, Class, quality, appraisal, etc.

The urban perimeter class: brown line, light brown fill, thickness 2, attributes: Year of approval, area, perimeter, year of projection, public restrictions. The restrictions associated with a combo type domain And hyperlinked to a document.

It is just an example, finally, what you would have are the categories, classes and properties ready to be able to construct data. It would only take to select that I will work on the real estate layer, draw the object and at the end of it the form is raised so that you can enter the cadastral key.  ... just build!

Then, when I query the object, I would lift the properties of that building, existing in the columns indicated in the associated table, the link to the associated photos, etc.

Gtools bentley map What else

For now the wizard has entertained me, but it would seek to combine those GIS functions that Bentley Map brings and develop some that are not so practical. Without forgetting what Geographics did and what is still necessary, such as transferring, removing or putting attributes, updating area / perimeter to xml, connection with Google Earth, display of attributes ...

It's funny, that as I work, I realize that Bentley thought about everything when he implemented xml on the V8 dgn, a big smoke from 2004, topics that he expected to solve in the Be together To which I do not know if I will be able to attend because the formal invitation comes to me at a disadvantage. Then to Bentley Map they have been implementing practically what any GIS user occupies, unfortunately not in the functional logic of a non-specialized user or that comes from another brand of software.

The challenge is interesting, there I tell you.
