  • Startup: Askaro – Why not to ask your neighbourhood for local events

    2

    Recently there were some news about Eduardo Manchón, the co-founder of Panoramio, leaving Google and the Panoramio team. After four and a half year he wants to address to his new task at Askaro. He stated in this blog post at Panaramio:

    Panoramio is the coolest thing I have ever done. I went through the greatest adventure of my life with this project. However for some reasons I can’t really explain I like changes and challenges, so it is time to move on to a new project.

    I’d like to make a short introduction about Askaro and give you an idea what it is all about:

    What is it?

    The founders call Askaro a hyperlocal site to exchange information where it matters the most: our neighborhoods, our places or work, etc. It can be used to ask a question which is realted to a specifc area of place. People who live there or live near by, are locale experts and can simply answer your question. Basically it is a system about georeferenced questions and answers.

    There are many possibilities to use this site, for example as tourist guid, resteraut review site or event planner. The founder see the site as experiments and are looking forward for feedback to improve the service and make it user driven.

    The name “Askaro” comes from “Ask around”.

    How does Askaro work?

    Askaro combines geolocation, question and answer model and reputation, as basis of its inner workings. Questions are asked, or placed, in a specific area of a city, in order to reach out to the people who live or intimately know the area and are capable of answering them. An analogy would be to stick a flyer at your local grocery store to reach out only to passersby, or people in your neighborhood.

    Answers can be voted once as “Good” or “Bad” by anyone, which have the effect of moving them up or down.The question’s author can also designate a specific answer as the “Best answer” if he or she considers it the most useful or appropriate one. Best answers turn green and move to the top.

    The number of votes and the answers marked as “best answer” are used to calculate the reputation score of a person, which is a measure of how valuable is someone’s contribution and how useful and trustworthy are his answers. The users with the best reputation in a city can be found in the “Local Heroes” page.

    Technology used

    Askaro server side code is written in python, and runs in the app engine, google’s cloud computing offering. Client side javascript relies on jquery.

  • Rebuild Google Earth in your Browser

    1
    Is it possible to build a full functionality Google Earth site in your Browser using the Google Earth API?

    Since the Google Earth Plugin was introduced for all major Browsers it is possible to transfer Google Earth Navigation and part of the functionality to the Browser. After early problems with the plugin (browser compatibility, performance, etc.) I was surprised how well the plugin can be installed (with Firefox 3, without restarting the browser) and used.

    The Google Earth API allows to embed location relevant information in an 3D Environment similar to the concept of the Google Maps API. I assume the functionality will of the API would be extended as it was (is) the case with the Google Maps API. It can be assumed that there will be a full functionality Google Earth in the Browser soon, or there will be completely new combinations of data and functionality accomplished by the creativity of the geocommunity.

    One Example might be the work of themanticmapping.org with the Earth Atlas.

    If you be aware of other great applications or services using Google Earth API. pleas post them in the comments.

  • Finding Addresses in Austria

    0

    I have tried to compare the big three search engines, Google, Yahoo and Microsoft Live in their functionality and usability for finding address locations. Address Geocoding is an important field of the GeoWeb and should be not problem for these three companies, but during the test I identified enormous deficits or a complete lack of these functionality.

    Test address was: Europastrasse 4, 9500 Villach, Austria. This information should be more than enough to visualize the exact location on the map.

    Lets Start with Microsoft Live Search. In my test this service completely fails. First of all if you try to enter the address in the search box of the ordinary Web Search you get some results which may be related to the address but it was not checked that the entered string represents an address (complete lack of semantics). Therefore, I changed to maps.live.com, to see if I can locate my address here. First of all you have to change the mode from the default (businesses) to locations. Then I entered the address to search. The results displays the map near Villach but far away from the correct location. Live maps do not have address geocoding for Austria. Hence, it cannot be recommended to search for Austria addresses.

    The next service I tested was Yahoo Local Maps. Similar like Live Search it was not possible to visualize the address from the normal web search. In the Yahoo Local Maps mode it is possible to enter the address in the search field. The result does not perfectly fit but it is close. Additional you get a hint that the exact address cannot be found but the nearest address is visualised. In this case much better than Microsoft Live Search.

    At least I tested the market leader Google. And it is the test winner of my small experiment. By entering the address as search string the first result is a small map, which visualizes the exact location of the address. From this small view you can directly change to Google Maps. Of course also Google Maps locate the address without any problems through the search box.

    So try it for yourself and tell me your Experiences.

  • EveryScape – StreetView inside buidings

    0

    EveryScape is a web service similar to Google StreetView but it allows also indoor navigation. Therefore it is possible to navigate though the streets of an city and go inside buildings along the city. Of course only public buildings are recorded.

    EveryScape uses Adobe Flash technology for visualisation.

    Excerpt from their homepage:
    “EveryScape’s patented HyperMedia Technology Platform allows anyone with a browser to experience a first-person, eye-level walk down a scaped street, gathering and sharing information on businesses and attractions, entering a store and shopping, checking the menu and reviews of a restaurant or the upcoming performances of a theater.”
    Currently EveryScape is in beta and parts of following cities are included:

  • Yahoo! Geo-Web Services

    0

    Yahoo’s announcement of its Internet Location Platform will be of interest to web developers and programmers interested in geolocating data. The platform uses something called Where on Earth ID (WOEID), a numerical tag that is associated with a given location; it can be used to obtain geographic coordinates but also spatial relationships (e.g., a city is inside a country, has a postal code, is next to another city).

    Yahoo! Internet Location Platform

    Welcome to the developer preview of the Yahoo! Internet Location Platform. The Yahoo! Internet Location Platform provides a resource for managing all geo-permanent named places on Earth. Our purpose in creating the Internet Location Platform is to provide the Yahoo! Geographic Developer Community with the vocabulary and grammar to describe the world’s geography in an unequivocal, permanent, and language-neutral manner.

    The Internet Location Platform is designed to facilitate spatial interoperability and geographic discovery; users can traverse the spatial hierarchy, identify the geography relevant to their users and their business, and in turn, unambiguously geotag, geotarget, and geolocate data across the Web.

    Getting Started

    1. Get an Application ID
    2. Read the online documentation
    3. Fire up a web browser or your favorite scripting language and explore the world

    Using the API or Web Service

    Overview

    In simple terms, the Service allows you to look up the unique identifier – called the Where on Earth ID, or WOEID – for almost any named place on the Earth; it also allows you to resolve a WOEID you have received from a third party – such as Fire Eagle™ or Upcoming – to the place it represents.

    The API is accessed via HTTP GET; the following examples can be cut-and-paste into a web browser to view the results:

    Find the WOEID of a significant landmark:
    http://where.yahooapis.com/v1/places.q(’sydney%20opera%20house’)

    Rate Limits

    Currently, users of the Internet Location Platform are limited to 50k queries per day.

  • Must it always be Google Maps?

    1

    To visual geographic content most of the people I know use Google Maps. But must if always e Google Maps? in my opinion NO! Currently there are great alternatives out there, where you can do a lot more than with Google Maps. Interesting projects comming from the open source community. I think the main problem (at least in my country) is that people simple don’t know much about these possibilities, therefore I’d like to provide some links:

    On the Example page of OpenLayers a lot of differnt maps are shown, where you can get an idea what is possible and how it works.
