Sobre os Arquivos DGN As curvas de nível digitalizadas pelo IBGE (Instituto Brasileiro de Geografia e Estatística) foram geradas a partir de folhas rasterizadas e arquivos provenientes de impressoras off-set.
Sobre a Utilização de Dados DGN Os dados provenientes das cartas topográficas ainda são informações muito requisitadas atualmente. Durante a digitalização, apenas algumas curvas receberam os valores de elevação.
Um dica importante para os que trabalham com representação através de rótulos. Execute estes procedimentos para exibir no mapa apenas os rótulos das feições selecionadas. Para as demais feições, a geometria permanece sem representação.

Recently, CLIMsystems Ltd. analyzed future climate impacts on the Hazelwood brown-coal fired power station located 150 km east of Melbourne in the Latrobe Valley, Victoria, Australia. These impacts included changes in ambient temperatures. The power station produces around 10 terawatt (TW) hours of energy, supplying up to 25% of Victoria’s energy requirements and 5.4% of Australia’s energy demand. The power station is a heat-intensive operation and relies on water extracted from a dedicated cooling pond. The Australian Energy Market Operator has forecast that Victorians would use an average about 10,250 megawatts (MW) of electricity per day through the three days of the recent heat wave event. On a typical summer day Victorians use about 6600 MW a day. Blackouts have occurred in parts of Victoria, and fan numbers were down during the opening rounds at the Australian Open grand slam tennis event with some players expressing concern after heat exhaustion. Tournament officials finally enacted their “Extreme Heat Policy” (for temperatures exceeding 42°C or 108°F) and suspeneded matches on the outer courts for several hours. Over this stretch of several days in January Melbourne experienced its longest heat wave in more than a century.
Recall that it wasn't too long ago that Esri officially announced the deprecation announcement for ArcGIS 10.1 and the upcoming release of 10.2.1 - see the support blog for details. From Esri... With the ArcGIS 10.2.1 update to the Deprecation Plan, the pattern is changing from a once-a-year release format to new updates with every release. The Deprecation Plan is also expanding to cover apps, mobile, and ArcGIS Runtime SDK products.
We were reminded of these changes by our friend Tripp Corbin from Corbin Associates who has also provided a quick look at some of the most noteworthy updates in this latest release. This from Tripp:
Esri has recently announced the release of ArcGIS 10.2.1. It has several new enhancements to ArcGIS for Desktop which I think many of us will find very useful. I have not had the chance to install this new version yet so I don’t know how stable it is. As with any new update, I recommend installing on a test box first to make sure nothing goes horribly wrong with your workflows....
