Explore the Earth, Maps and Satellite Images

Google Maps and Google Earth are very common platforms today to explore maps and satellite images of the earth. But there are many other ways to explore the earth. Some are listed here.  1.   Earth Explorer This map is developed by USGS helpful to obtain earth imagery across available geo-spatial data types. Users can navigate via interactive map or text search to obtain Landsat satellite imagery, Radar data, UAS data, digital line graphs, digital elevation model data, aerial photos, Sentinel satellite data, some commercial satellite imagery including IKONOS and OrbView3, land cover data, digital map data from the National Map, and many other datasets. Users can search by exact location via the interactive map or input specific coordinates to view what data types are available. 2.   Sentinel Hub This platform developed by  Sinergise has Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysis. It can automatically archi

सेनाको संख्या घटाउने कि बढाउने

  #RightToRejectin2084   #WeWantRightToRejectin2084 देशमा चालू खर्च चुलिदो छ। चालू खर्च  र वित्तीय व्यवस्थापनको बोझ दिनानुदिन बढ्दा हालै ल्याईएको आ व ०८१/८२ को बजेट पुजिगत खर्चको हिस्सा १९% प्रतिशत भन्दा कम देखिन्छ। समयक्रम सगै विकासका लागि झन् ठुला र महत्वकान्छी योजनाको माग बढीरहदा यस्को स्रओत कहावाट जुटाउने भन्ने समस्या देखीन थालेको छ।  सरकारको अपेक्षीत राजश्व संकलनले चालु खर्च नै मुस्कीलले धान्ने अवश्थामा विकाश वजेटको व्यवस्थापन नै अहिलेको मुख्य चुनौति रहेको छ। चालु खर्च काम गर्नका लागी अनेको प्रयासहरु गरिएका पनि छन। सरकारले विभीन्न समयमा विभिन्न सरकारी निकायहरु गाभ्ने तथा खारेज गर्ने घोषणा पनि गरेको छ तर तिनको कार्यान्वयन प्रभावकारी रुपमा हुन सकेको छैन। यस्तै अनेकन प्रयास र चर्चा परिचर्चामा रहेको कुराको सेनाको संख्या। सेनाको संख्या घटाउने बढाउने विषयमा विभिन्न तह तप्कामा छलफल तथा वहस चलिरहेको छन। सेनाको संख्या घटाउने बढाउने  विषयमा दुवै पक्षमा जोडदार आवाजहरु सुनिन्छन। सेनाको हालको संख्या लगभग ९८००० जना रहेको छ। देशको सुरक्षा संयन्त्रको प्रमुख हिस्सा रहेको नेपाली सेना हाल मुख्य त व्

Dolomite in Nepal

  Dolomite occur mainly in Mahabharat range in Dhankuta, Khotang, Udayapur, Sindhuli, Dolakha, Kavre, Kathmandu, Makwanpur, Dhadhing, Syangja, Palpa, Baglung, Gulmi, Arghakhanchi, Dang, Pyuthan, Sallyan, Rolpa, Rukum, Jajarkot, Surkhet, Dailekh, Jumla, Achham, Doti, Bajhang, Bajura, Baitadi and Darchula districts in the Lesser Himalaya and in some parts of Higher Himalaya and Tibetan Tethys (Inner Himalaya) region (Kaphle, 2005, 2020).  The quality of dolomite depends on its chemical composition like MgO%, CaO%, SiO2%, Al2O3%, Fe20%, LOI%. Depending on these oxides it can be used in different industries. Dolomite is a potential source of metallic magnesium. It is used to manufacture soral cement and also in refractories, high magnesium lime, flux for iron and steel industries, ferroalloy industries, fertilizer industries and acid water treatment plants. Dolomite can be directly used in agricultural field to neutralize acidity and also to make up the loss of magnesia in soil. MgCO3 is u

Right to Reject

  "Right to Reject," or "None of the Above" (NOTA)  option in election papers, allows voters to choose an option that signifies they do not support any of the candidates standing in the election. This option is intended to give voters a formal way to express dissatisfaction with all candidates and to potentially influence political parties to offer more suitable candidates. Though NOTA does not typically result in the annulment of the election or a re-election, it can highlight voter dissatisfaction and encourage political reform.  On January,2014, the Supreme Court has directed the government to provision the voters’ “right to reject” all candidates in elections. Its been 10 years past and still the Government and Election Commission have not shown any interest in implementing this decision and  the court ruling,  was not implemented in the 2017 and  2022 elections.  This  rule will allow a voter with an option to reject all the candidates mentioned on ballot paper

Seismic Survey: Notes of major uses

  Seismic Survey Suitable for mapping of layered sedimentary sequences Widely used in search of oil and gas. Small scale mapping of near surface sedimentary layers , location of water table,  Site investigation of foundation conditions (including depth of bedrock). In engineering site investigation, Vp and Vs measurement for near surface layers allows direct calculation of Poisson's ratio and estimation of elastic moduli, which provides valuable information on in situ geotechnical properties. Offshore geological surveys Refraction Reflection ( most widely used geophysical technique) Large/regional scale experiments for study of the entire crust or lithosphere. Estimation of depth of bedrock in foundation site investigation. In engineering purpose, derive relation between velocity and hardness of rock for quarrying operations, nature of landfill materials. Exploration of underground water in conjunction with resistivity methods (as there is a large difference in velocity of dry and

Granites in Nepal Himalaya

Granites are distributed in three parallel belts in Nepal Himalaya 1.      Paleozoic Granites ·        They are  Cambro-Ordovician age. ·        They are found in thrust sheets of Lesser Himalaya, Kathmandu Nappe and Dadeldhura Nappe. ·        The granites are made up of biotite-rich and tourmaline-rich varieties . ·        They are closely associated with the adjacent gneisses, which display a similar mineral composition. ·        Several concordant, tabular granite bodies, up to 200 m thick, are intruded. ·        Some well-known bodies are Palung Granite, Agra Granite, Dadeldhura Granite   2.      Higher Himalaya Leucogranites ·        They are of Tertiary age and occur as several plutons, very many dikes, and veins. ·        Early to Middle Miocene  Leucogranites ·        These igneous rocks are mainly concentrated towards the top part of the migmatitic gneisses in the Tibetan slab ·        Tourmaline is so frequent in the granite that they are sometimes called the tourmaline grani

Physiography of Nepal

  A south to north profile across the Himalaya shows the following physiographic division: . • Terai • Siwalik Range  with dun valleys • Mahabharat Range • Midlands • Fore Himalaya • Great Himalaya • Inner Himalayan valleys • Tibetan marginal ranges.   Terai The Terai is the plain land on the southernmost part. It consists of young river sediments (Pleistocene to Holocene sediments). It is also considered as the part of the  Ganga foreland basin.. The aerial width of the Terai  varies from about 30 km in west Nepal to about 40 km in central Nepal, and from 25 to 50 km in east Nepal.  The Terai slopes towards the southern Indian side and the elevation   difference between the Siwalik foothills and the Indian border ranges from 100 to 200 m.  Within the Nepal territory, there are three separate zones of alluvium observed south of the Siwalik hills based on which the Terai is subdivided into the three zones from north to south. Upper Terai or Bhabar Zone : The Bh
