What's the better strategy to persist Geo data?

#InterSystems IRIS #Databases #Data Model #Document Data Model (NoSQL)

I have an application with maps that render and edit geographic data in a some layers using KML - geo data represented into XML file with layers, polygnons, points and metadata associated with it. Some maps are in GeoJSON too.

Is it DocDB the better option?

Product version: IRIS 2020.4

Just for the info, few years ago, on Moscow's hackathon was a project SpatialIndex. Related article

The format is stable, use XML tools for data import/export into persistent classes.

The KML spec is a complex XML schema. See:

Into Postgresql it has PostGIS, because this complexity, in IRIS I need only use this XML import utility?

@Yuri Marx :
if you have the schema as XSD at hands
All you need to do is to open the XML wizard in IRIS Studio and it generates the whole packages for you

>>>

I used it rather intensive and a pack of 100+ classes from 1 XSD was no problem

@Dmitry Maslennikov
Is this also supported by VSCode?

If it was me I'd use the persistent DOM of QEWD-JSdb

https://github.com/robtweed/qewd-jsdb/blob/master/DOM.md

QEWD includes access to this.
