Allgemeines unsinn what I read

schrebergärtchen für elise

Das ist der Bereich, den du und ich in 50min von zuhause aus erreichen können:


Wenn wir uns das aber mal anschauen vom BHF Charlottenburg und Ostkreuz aus. Plus der Distanz von 60min kommt folgendes Bild dabei heraus:


Da kommen wir in der Schrebergarten Siedlung in Oberschöneweide raus. Oder in Köpenick, Grünau an der Dahme, Buch, Karow, Oranienburg, Hohen Neudorf, Heiligensee, Henningsdorf (deie letzten vier übrigens an der Havel).

Wie du siehst das ist alles noch ziemlich Stadtnah. Auch mit einer Stunde Reisezeit.

Quatschen wir noch mal drüber.

Wie er einen Koffer kaufen wollte

und mit einer Einführung in die google (fusion) tables endete:

Handgepäck ist eine gute Sache! So sehr wie mir all diese (Pseudo)Businessmen mit ihren schicken schwarzen Rollköfferchen auch auf den Wecker gehen, wenn sie sich am Gate noch fix vordrängeln und nach dem Landen nicht warten können bis die Anschnallzeichen erloschen sind bevor Blackberry, IPhone und Nokia angehen und jeder schnell der erste im Meeting sein will, so sehr muss ich auch gestehen, dass es wirklich Vorteile hat nach einem Flug nicht noch gefühlte Stunden am Band auf das Gepäck warten zu müssen.
Wirklich nichts geht beim Reisen über einen fitten, praktischen Rucksack so viel steht fest. Auf den letzten Tripps musste ich aber feststellen, dass mein guter Tatonka 75+ für fast jeden Tripp zu groß gewesen ist. Traurig aber wahr.
Das ist ein Grund für Handgepäck. Also benötige ich wohl auch sowas. Danke unserer Projektassitenz in Rom, die einzige Italienerin im Team, weiß ich, das man sowas bei CARPISA kaufen kann. Schnell mal Google angeschmissen und eine Liste mit Adressen gefunden. Aber woher weiß ich nun – als nicht ortskundiger Römer – welcher Laden der nächste ist? Da kamen mir die google (fusion) tables in den Sinn, die genau so etwas machen können, neben anderen Sachen.

  • Schritt eins: Liste der Adressen in ein Textdokument kopieren,
  • Schritt zwei: Mit ein bissl „Suchen+Ersetzen“ ein CSV Format daraus gemacht,
  • Schritt drei: CSV in Openoffice öffnen und in einer Spalte Straße und Stadt verbinden,
  • Schritt vier: Google drive öffnen,
  • Schritt fünf: „Create“, „More >“ und „Table (beta)“ wählen,
  • Schritt sechs: Tabelle hochladen,
  • Schritt sieben: „Visualize“ und „Map“ wählen,
  • Schritt acht: Spalte mit der Adresse zum geokodieren wählen.

Und so sieht’s dann aus:

Hier die Tabelle:

Ich finde ja so anwendungsbezogene Sachen immer gut, ne? Ich werde zu dem Laden am Termini fahren und mir einen Handgepäckskoffer im Sale kaufen. 🙂

That Is Why I Do Love My Job

Recently I got pointed by Twitter on a job description via the topic ‚GIS Forester‘ or something like that. Normally I mark those kinds of texts with a big ‚Read-later‘ tag, but forget about this anyway. This time I decided to read the text immediately and do not regret it. This description embraces so much of the reasons I love my CV for and convinces me that I took the right choice. It was one of those fundamental decisions to make which turn out to be right in the long run.
Anyway this text combines in a short way all the things I consider or have in my subconscious when thinking about my profession. But I do not want to keep you longer on the tenterhooks. Here it comes (quoted one-on-one from the source mentioned below):

Geography and technology matter to foresters

Foresters and conservation scientists manage the use and development of forests, rangelands, and other natural resources. Among other things, these lands supply wood products. They serve as sites for recreational activities and provide habitats for wildlife and help sustain natural water systems. Some workers advise private landowners on the use and management of their land and many use geographic information system (GIS) technology to design and implement programs that make the land healthier and more productive. Others work to conserve or restore public or private lands. Conservation scientists and foresters often specialize in one of several areas, such as soil conservation, urban forestry, pest management, native species, or forest economics.

Foresters oversee our Nation’s forests and direct activities on them for economic, recreational, conservational, and environmental purposes. Individual landowners, the public, and industry own most of the forested land in this country, and they require the expertise of foresters to keep the forests healthy and sustainable. GIS technology is used by 21st Century foresters in the development and implementation of healthy forest plans to keep the forests free from disease, harmful insects, and damaging wildfires by planning, for example, when and where to plant trees and vegetation and when to cut timber. It also may mean coming up with ways to make the land profitable but still protected for future generations.

Foresters have a wide range of duties, depending on whom they are working for. Some primary duties of foresters include drawing up plans by hand or with the aid of geospatial technology (GIS, GPS, and remote sensing) to regenerate forested lands, monitoring the progress of those lands, and supervising harvests. Land management foresters choose and direct the preparation of sites on which trees will be planted. They oversee controlled burning and the use of bulldozers or herbicides to clear weeds, brush, and logging debris. They advise on the type, number, and placement of trees to be planted. Foresters then monitor the seedlings to ensure healthy growth and to determine the best time for harvesting. If they detect signs of disease or harmful insects, they consult with specialists in forest pest management to decide on the best treatment. Foresters use a variety of data collection tools and geospatial technologies to help them more efficiently make decisions involving large forested acreages and thousands of plants and trees.

Throughout the forest management and procurement processes, foresters often are responsible for conserving wildlife habitats and creek beds within forests, maintaining water quality and soil stability, and complying with environmental regulations. Foresters must balance the desire to conserve forested ecosystems with the need to use forest resources for recreational or economic purposes. For example, foresters increasingly are working with landowners to find ways to generate money from forested lands, such as using them for hunting or other recreational activity, without cutting down trees. A major concern of foresters is the prevention of devastating wildfires. Using a variety of techniques, including the thinning of forests and controlled burns (to clear brush), foresters work with governments and private landowners to minimize the impact of fire on the forest. During a fire, they work with or supervise firefighters and plan ways to contain the fire.

Some foresters, mostly in the Federal Government, perform research on issues facing forests and related natural resources. They may study tree improvement and harvesting techniques; global climate change; protection of forests from pests, diseases, and fire; improving wildlife habitats; forest recreation; and other topics. Geospatial technology is used extensively in these research and modeling activities. State foresters may perform some research, but more often work with private landowners in developing forest management plans. Both Federal and State foresters enforce relevant environmental laws, including laws on water quality and fire suppression.

Relatively new fields in forestry are urban forestry and conservation education. Urban foresters live and work in larger cities and manage urban trees. They are concerned with quality-of-life issues, such as air quality, shade, beautification, storm water runoff, and property values. Conservation education foresters train teachers and students about sound forest stewardship.

Foresters and conservation scientists use a number of tools to perform their jobs. Clinometers measure the heights of trees, diameter tapes measure tree diameters, and increment borers and bark gauges measure the growth of trees so that timber volumes can be computed and growth rates estimated. Remote sensing (aerial photographs and other imagery taken from airplanes and satellites) and GIS data often are used for mapping large forest or range areas and for detecting widespread trends of forest and land use. Once a map is generated, data are digitized to create a computerized inventory of information required to manage the land and its resources. Hand-held computers, GPS receivers, and Internet-based applications are widely used.

Work environment. Working conditions vary considerably. Some foresters and conservation scientists work regular hours in offices or laboratories, but others may split their time between fieldwork and office work. Independent consultants and new, less experienced workers spend the majority of their time outdoors overseeing or participating in hands-on work. Fieldwork can involve long hours alone.

The work can be physically demanding. Some conservation scientists and foresters work outdoors in all types of weather, sometimes in isolated areas, and consequently may need to walk long distances through densely wooded land to carry out their work. Natural disasters may cause foresters and conservation scientists to work long hours during emergencies. For example, foresters often have to work long hours during fire season, and conservation scientists frequently are called to prevent erosion after a forest fire and to provide emergency help after floods, mud slides, and tropical storms.

Foresters employed by Federal and State governments usually work 40 hours a week, but not always on a standard schedule. In field positions, foresters often work for long blocks of time—10 days straight, followed by 4 days off, for example. Overtime may be necessary when working in firefighting, law enforcement, or natural-disaster response.

Geography and technology matter to foresters

The work of foresters is very much tied to the Earth and its geography. Knowing where things are and how they relate to one another is central to the work that foresters and forest researchers do. A definition brings this into focus: Geography is the study of the world and all that is in it: its peoples, its land, air, and water, its plants and animals, and all the connections and relationships among its various parts.

A forester’s ability to explore these geographic components as they conduct their research is changing rapidly because of technology advancements. Recent improvements in field data collection, computers, information processing, and automated mapping allow scientists to juggle volumes of spatial data with increased speed and accuracy (essential in a wildfire situation). Geographic Information systems (GIS) technology, combined with remote sensing (RS) and global positioning systems (GPS) are yielding great advances in scientific research. While the basic scientific data collection and analysis techniques are unchanged, a new breed of foresters is emerging armed with advanced geospatial tools and processes.

Foresters and conservation scientists use GIS software to visualize and analyze interrelated layers of geospatial data (information about a place represented by points, lines, polygons, and images). They employ spatial thinking processes. Driving their work are geographic questions: How does thinning the forest affect local biodiversity? What’s the connection between vegetative mutations and local water quality? Do plant and tree disease spread with some of geographic pattern? Why is there soil erosion here while that region of forest is stable?

QGIS developer: Entwickeln für ein Open Source GIS

unglaublich spannend. acht Jahre arbeiten – unendliche Stunden und ein Projekt. zumindest eine Visualisierung wert. Das hat ein gewisser Nathan mal getan. Das Ergebnis seht ihr hier. Spannend.

interested in the history of map projections?

die GIS LOUNGE hat einen Hinweis auf ein Buch über Mapprojections gepostet (John P. Snyder’s 1987 “Map Projections: A Working Manual”). Das ist interessant um einen Einblick in die diversen Projektionssysteme zu bekommen, bzw. um Wissen aufzufrischen.

The USGS has posted a scanned file of John P. Snyder’s 1987 “Map Projections: A Working Manual” online in PDF  and DjVu format.
