Changes in the lines on the map of Shaanxi, Shaanxi outline traces of urban change; not changed is latitude and longitude, change the map area the size of the improvement of transport networks, urban blocks the rapid expansion and landmarks, tourist attractions, the increase in .

Through the map changes, the pace of change in urban development in Shaanxi clearly visible. Can be said that reading a map is like reading a history, read a life.

Because the city changes so rapidly, Xi'an Map Publishing had not updated over the last year or even a version of an updated version in 2023, but separated several months is necessary to reprint.

Xi'an 60 years of built-up area expanded 26-fold

In recent days, this reporter visited the surveying Surveying and Mapping Institute of Xi'an, Xi'an Map Publishing House, a change in maps to the people about the tremendous changes in the city's landscape.

Look at the Republic of China Xi'an City Map: liberation of the Xi'an city from east to west about 3.4 kilometers from north to south about 2.6 km, with a total length of 11.9 kilometers weeks, with an area of about 10 square kilometers. "At that time the map is really tiny, palm-sized one, thus limiting the scope of the old city, full of houses." Surveying and mapping work done Lv Shiguo 23 years old, said he engaged in 70s last century, when the surveying and mapping work, the to The office is a piece of cottage and small alleyways, then felt a high only walls and bell tower. "Take the time for the West Street and also some small bungalow, alleys, small homes, surveying and mapping, often in the inside turn one, the map changes so fast, it is in the most recent decades. East and West, All roads lead to enjoy an extension of the road, railway, highway, proudly presented in front of the past, how can there be such a map? current maps, Founder of the old city sitting central, surrounded by the development around the new area. "" I remember in the last century 70's, When I came to Xi'an to school, the walls are vegetable circle. "

Recently, Mayor of Xi'an Chen roots in a media interview, said that the founding of the completion of the initial area of Xi'an, just only 14 square kilometers, confined to the walls circle.

Map of the city more and more like a "net"

"The map can best embody the changes in Xi'an, 60 years. Xi'an map is no longer a city just like they should, and now I feel like a map of a network. In the production, I have deliberately used the bright yellow lines to show a ring, Ring, Ring, Ring speed. "Xi'an Cartographic Publishing House editor, Liu Xinhua said, for almost eight years, Xi'an zone map editor, her deepest thoughts and feelings in this regard.

Pointing to the table of the various periods of Xi'an maps, Liu Xinhua, said: "You see, this is a map of the last century 80's, Xi'an city has 'freed' wall bound, from a ring expansion to a second ring; the last century, 90s onwards, Xi'an, increased road and bridge, the Second Ring, Ring Ring Two, widening urban transport framework; the last 10 years, and gradually shaping of radiation from a new 'big Xian' metropolitan area, a new landmark in Xi'an in large numbers. "

Subway Line No. 1,2, proudly presented the new version of the map. "In the past on a catch-all situation on the map can not meet the needs of people with the map. A capacity of no less than a map, we developed various types of maps for different groups of people, so that more and more species-rich maps."

Preparation of as fast as the pace of development

"Today, unlike in the past Xi'an Map Publishing has long been updated annually and even a version of an updated version in 2023, but separated several months is necessary to re-publication, because of changes in the city fast." Cuiwen Hong said that the map revision every year, Xi'an is still not keep up with the pace of development.

Cuiwen Hong said: "In particular, in recent years, urban construction can be said that with each passing day, urban development is obvious to all, Xi'an Third Ring Road and the Ring Second Ring Expressway repair after another pass, Xi'an High-tech Zone, through the open areas, Qujiang New Area and Chanba ecological zone and several other development zone gradually formed, going up an endless stream of commercial housing, extending in all directions dense spider web of urban roads, bus lines distributed in the streets, these figures could not finish the changes so that we map publishing staff 'unhappy', worry what the it? melancholy as fast as our map prepared by the pace of urban development. "" expanding to the outskirts of Xi'an city, roads in the extended, correspondingly, we are also expanding the scope of the preparation of the maps, such as the 2008 version of the Xi'an city map, west to West Ham at the junction of the east, Hung Chin-Subdistrict, north to Weiyang Lake, south to University City, while the map sheet format size is limited, which we had to reduce the map scale to accommodate the additional traffic information. "Cuiwen Hong Xiao and said, "the contents of the resulting map of the density increase, such as Xi'an city wall significantly reduced within the map can only be labeled with the position of the role of some surface features, such as the Bell and Drum Tower, Lianhu Park, the provincial government, Kaiyuan mall and so on, other, more Multi-point position only aggrieved by the point of being out of the map, sacrificing the. "

Drawing the map can not keep up tall buildings cover

Such a number of people who every day a true record of the changes in Xi'an, Xi'an to their footprints all over every corner of this land there is any hint of subtle changes are not escape their eyes ... ... they are, that is, surveyor. High-rise buildings, roads, urban development is a microcosm of surveying and mapping instruments are now faced with constantly updated, mapping technologies are increasingly developed into a map area have increased today, has been doing this for 20 years, retired surveyor Lvshi Guo, Zhang Wenxuan with emotion: " We draw the map can not keep up build tall buildings, repair roads! "

73-year-year-old Zhang Wenxuan recalls that "traffic entirely away, drawing entirely hand-calculation by abacus, hand computer."

By 80 years after the last century, cities began large-scale construction, surveying members of the working methods have also changed, science and technology makes the mapping work has made a qualitative leap.

71-year-old Lvshi Guo said: "Today, GPS satellite positioning systems, total stations, aerial mapping, satellite remote sensing with charts and other advanced equipment and technology to be used in succession, mapping into the digital age, in a simulated period of a few months to complete the Survey and Mapping The work is now only a few days can be completed, and surveying and mapping data and more accurate. "They lament: that such a high speed, rapid urban development, the need for, or can not keep up.

"M" shaped road map of the main frame has leapt to

Is responsible for the preparation of maps of Shaanxi Province for 10 years editor-ming Ouyang, in Shaanxi on the map to see the biggest change is the transport network, with Xi'an as the center extending in all directions, "m" shaped modern highway transportation network has been formed, just like leap onto the map.
