Pros & Cons
GE Smallworld
Pros
- Purpose-built connected network model for utilities, with industry-specific applications such as Electric Office and Gas Distribution Office.
- Its Version Managed Datastore supports concurrent long-running edits and merges them without data loss.
- It is highly customizable through Magik and Java on the JVM.
- It integrates with GE Vernova GridOS and ADMS, and with SAP and IBM Maximo through Business Integrator.
- It can run on AWS, Azure or Google Cloud and offers browser-based role interfaces.
Cons
- Reviewers describe license and maintenance costs as very high, and there is no public pricing.
- Reviewers say the desktop interface looks dated and is not friendly.
- Exporting data is awkward and often needs a conversion tool such as FME.
- Its value-added tools focus narrowly on utility networks, and one reviewer found its general mapping and spatial queries limited.
GeoServer
Pros
- Free under the GPL with no per-user or per-server license fees.
- It is the reference implementation of OGC WFS and also supports WMS, WCS and WMTS, so any standards-compliant client such as QGIS or ArcGIS can use its layers.
- It connects to a wide range of data sources, including PostGIS, Oracle Spatial, Db2, MongoDB, shapefiles, GeoTIFF and ECW.
- It has flexible security built on Spring Security, with LDAP, Active Directory, CAS and X.509 authentication and per-layer access rules.
- A G2 reviewer singled out custom map styling with SLD and CSS.
Cons
- It is a map server only, with no asset registry, work orders or maintenance features.
- There is no vendor support included. Help comes from community lists or paid third-party providers, and a G2 reviewer complained about a lack of back-end support.
- An independent load test found poor raster reprojection quality and a brief outage at around 70 concurrent users.
- Self-hosting needs Java server administration and GIS expertise.
