PaDesktop level

Quantum GIS. Iyo yakanyanya kuitiswa munzvimbo yeAnglo-Saxon, kazhinji ichiperekedzwa neGrass.
GRASS. Iyo yekare OpenSource system, ine pekutanga mune raster.
Saga. Akazvarwa kuGerman, aine tarisiro yepamusoro pakutsvagisa.
Ilwis. Initiative iyo yakazvarwa muHolland, uye kunyangwe ichiuya kubva pakati pemakumi masere, budiriro yayo pasi pekubatanidzwa kwenharaunda haina kunaka.

gvSIG. Pamwe inonyanya kushambadzirwa OpenSource kunyorera munzvimbo yevaSpanish, uye pamwe iyo ine hunyanzvi hwekuona nyika. Parizvino, zvinopfuura zana zvezvinyorwa zvangu zvinonongedzera kune ichi chishandiso.
SEXTANTE. Yakasimudzirwa neUniversity yeExtremadura, mubatsiri mukuru kune gvSIG, kunyangwe paine maraibhurari eOpenJump, Kosmo uye inotobatana neGRASS.
UDig. Uku kuchena, kana kushoma kwakaparadzirwa kukura nekwaniso yepamusoro, yakagadzirwa nekambani imwechete yePostGIS, GeoServer neGeotools.
Kosmo. Ini ndinoshanda kubva kuOpenJump, ndakazvarirwa kuSpain.
OpenJump. Nhaka yechirongwa cheCanada chinonzi Jump, icho chakamiswa.
CatMDEdit. Iyi metadata mupepeti.

Paway server level

MepuServer. Yakapararira kwazvo, kunyangwe iine inononoka kufambira mberi mukuvandudza uye kusangana kupfuura Geoserver.
MepuGuide OS. Inotsigirwa ne AutoDesk, yakasimba kwazvo.

GeoServer. Inogona kunge iri iro rakanyanya kushandiswa data dhata.
GeoNetwork. Iyo metadast catalog maneja, yakanakira geoportal kana yekuchenesa imba.
