Announcing the release of QGIS 1.3.0 ‘Mimas’

Introduction

Quantum GIS (QGIS) is a user friendly Open Source Geographic
Information System (GIS), licensed under the GNU General Public
License, that runs on Linux, Unix, Mac OSX, and Windows. QGIS is Open
Source software and its free of cost. It supports vector, raster, and
database formats (including the most common ESRI ShapeFile and
geotiff). QGIS supports a wide variety of plugins to do things like
display tracks from your GPS, and much more. They can be easily managed
through the Plugin Manager.

As an open source project, we provide support for using QGIS via our mailing lists and bug tracker:

Sponsoring

We are still looking for sponsors to help us cover the costs of holding
our second QGIS developer meeting in Vienna, Austria from 5-9 November
2009. If you are interested in supporting us, please visit: http://qgis.org/en/developer-meeting.html for more details!

Whats new in Version 1.3.0?

Please note that this is a release in our ‘cutting edge’ development
release series. As such it contains new features and extends the
programmatic interface over QGIS 1.0.x and QGIS 1.2.0. If an unchanging
user interface, programmatic API and long term support is more
important to you then cool new and untested features, we recommend that
you use a copy of QGIS from our Long Term Support (LTS)1.0.x release
series. We have removed the ‘unstable’ designation from our development
release series because it creates the incorrect impression that these
release are more likely to crash. The development releases are usually
quite stable to run, but introduce new features and API additions which
some people may wish to avoid.

This release includes over 30 bug fixes and enhancements over the QGIS
1.2.0 release. In addition we have added the following new features:

OSM plugin & provider updates:

  • new OSM style files.
  • new icons.
  • dialog text updated and completed.
  • Saving OSM into file functionality was improvements.
  • fixed some problems with encoding… ascii to utf-8.
  • all OSM layers are automatically removed after disabling OSM plugin in plugin manager.
  • other OSM related bugfixes.

Other notable features and improvements in this release

  • Marker size is now configurable when editing a layer.
  • Incorporation of the analysis library into the mainstream release.
  • Identify features across multiple layers.
  • Added a new plugin for carrying out raster terrain analysis (computing slope aspect, steepness etc).
  • A reshape tool to apply to line/polygon geometries. The part
    of a geometry between the first and last intersection of the reshape
    line will be replaced.
  • Added snapping to current layer in measure dialog.
  • Added ability to select the primary key for views.
  • Zoom to a coordinate by entering it in the status bar coordinate display.

The issue with crashing or hanging when zooming into polygon datasets on some operating systems should now be resolved.

Download your copy

Binary and source code packages are available at http://qgis.org/en/download/current-software.html

Visual changes

Here are some of the most noticeable changes in this release:

Reshape features. The reshape tool allows you to change the geometry between two vertices.


Measure snapping. When using the measure tool you can now snap to vector features.

Terrain modelling. We are starting to slowly add more native (i.e. non
GRASS based) analytical tools to QGIS. In this release, a new plugin
was added for carrying out terrain modelling activities.

Marker Sizes. The marker sizes and display behaviour is now more configurable to give you the digitising environment you prefer.

Cloudmade – Make Maps Differently

sâmbătă, februarie 28th, 2009
Am gasit un site continand foarte multe harti din Europa. Inca nu am testat sa vad precizii, dar pentru scopuri informative, e excelent.
http://cloudmade.com/
Cam asta spun producatorii:

CloudMade Make Maps Differently

CloudMade

OpenStreetMap, the community mapping project which is making a free map
of the world. Our aims are to continue the democratization of geo data
and to expand access to open geo data through a range of simple yet
powerful tools and APIs.

Our first set of APIs allow developers to integrate high quality maps into mobile and web -based applications.

Investirea lui Barrack Obama

joi, februarie 26th, 2009
Mai mult pentru fotografi:
 
Aceasta este o fotografie de lainvestirea lui Obama, in care se poate vedea in detaliu fiecare chip
din multime. Folosind cursoarele din partea stanga sus ( sau dublu
click ) se poate accesa si mari fiecare zona din imagine (asteptati
cateva momente si imaginea se va clarifica). Fiecare persoana putea fi
identificata dupa eveniment in cazul unui eveniment nedorit.
Fotografia a fost facuta cu o camera robotizata de 1474 megapixel (o rezolutie 295 de ori mai mare decat a unei camere obisnuite).

Merita sa aruncati o privire!

NORC: See, look, explore

Super site – as fi vrut sa fac ceva similar, insa se pare ca nu sunt singurul care a avut initiativa .
http://www.norc.ro/
 
…cu mentiunea ca pozele sunt la nivelul anilor 2002-2004, din cate mi-am dat eu seama. Chiar si harta luata din google nu mai recenta. Dar conceptia, cel putin, e extraordinara.

A aparut Quantum GIS 1.0 “Kore”

marți, ianuarie 27th, 2009
Dupa cum am spus si in titlu, se poate descarca de la http://www.qgis.org/ insa ne va trimite la http://trac.osgeo.org/osgeo4w/ de unde se descarca un installer numit OS4GeoW prin care se va instala, online, versiunea dorita. Ma rog, nu e una din metodele mele favorite, dar asta e situatia, ne adaptam.
Conform spuselor dezvoltatorilor, va aparea si o versiunea standalone, ce va putea fi descarcata in mod independent de pe site-ul acestora.

Gazetteer A
gazetteer is a list of place names and their coordinates. The files you
can download here are for use in DIVA for automatic georeferencing (to
assign coordinates to places). The files should be placed in the 
gazet directory. (old, use Biogeomancer). They can also be used to map localities, however you can download more recent files from NIMA
U.S. National Imagery and Mapping Agency’s (NIMA) database of foreign geographic feature names DBF -

Formats

The files have been compressed and grouped in ZIP files. You can use
programs such as 7-zip, PKZIP or StuffIt to decompress the files.
Vector data are stored as ESRI shapefiles
Grid (raster) data are stored as DIVA gridfiles
Each "shapefile" consist of at least three actual files. This is a
commonly used format that can be directly used in Arc-anything,
DIVA-GIS, and many other programs. It can be imported to most other GIS
programs. Shapefiles contain a single class of "vector" data such as
points, lines, or polygons.
Gridfiles are used in DIVA-GIS. From DIVA-GIS they can be exported to a
number of other grid formats including IDRISI and Arc or to shapefiles.
(More info on format;
for developers).
A gridfile with "country mask" indicates that the areas outside the
selected country are masked out. For these areas, the value is "NODATA"
(indicating the absence of data for those cells). For the other
gridfiles, NODATA is only used for areas covered with water, except for
the land cover grids, on which water is a separate class.
A DBF (dBase file) is a dbase format database table. 

Resolution

The resolution is the size of each grid cell
expressed as the length of one side of one (square) cell. The units are
in (arc) degrees, minutes or seconds. When the cell size is small
(e.g., 30 seconds), resolution is high. The size in square meters
varies with latitude . A cell with a 30 seconds resolution is about 0.8
km2  at the equator and smaller at higher latitudes. High resolution
files for large areas (countries) can be very large. This means that it
may take a while to download these files, and that you will need a fast
PC to work with them.
