Hazard Data Distribution System (HDDS) tutorial

Geospatial data, particularly imagery, are crucial during disaster response.  The USGS has a wonderful web-based application called the Hazard Data Distribution System (HDDS) that provides the capability to download incident related imagery.  This video provides a short overview of HDDS, demonstrating how to you can use HDDS to locate and download imagery for your area of interest.  Please note that if you are involved in disaster response you will need to request permissions from the USGS to obtain access to the licensed imagery.  For more info on  HDDS please read the help pages.

  1. الفرق بين لدغة البعوض و بق الفراش
    البعوض يلدغ فى اى وقت يتواجد به الانسان ام البق فيلدغ فى الليل فقط .
    لدغات البق تكون اكثر شدة وآلم من لدغات البعوض .
    تكون منطقة اللدغات على الجلد اكثر اتساعاً من لدغات البعوض وأكثر وضوحاً .
    لدغة البق يتواجد بها جزء صغير داكن عكس لدغة البعوض والتى لا يتواجد بها هذه البقعة الداكنة .
    فى كلا الأحوال ورغم الفروق بين لدغة البعوض و بق الفراش إلا أن كلتا الحشرتان يتشابهان فى بعض الأمور و يتسببان فى
    الألم والحكة المؤلمة والإزعاج والقلق والتوتر ويجب القضاء على كليهما وأفضل الحلول هو التعاقد مع شركة محترفة للقضاء عليهما
    وربما يكون البعوض أسهل فى التعامل معه وقتله بالمبيدات الحشرية الموجودة بالأسواق ولكن البق يجب التعامل باحترافية ومعرفة
    خباياه للقضاء عليه وتعد شركة المصطفى من افضل شركات مكافحة الحشرات وتتخصص فى القضاء عليها بأفضل وأقوى الامكانيات

    من حشرات وخلافه ، اتصل على المصطفى الآن فى أى وقت وعلى مدار اليوم بأكمله وتمتع بالخصومات الكبيرة واجعل بيتك خالى من أى نوع من الحشرات .
